Problem migrating from Archetypes to Dexterity via @@atct_migrator

Plone Support Administering Plone sites

Hi

After upgrading our Plone-Site from 4.3.15 to 5.0.7 I also wanted to migrate the content which I asume is Archetype to Dexterity as I guess, this is the recommended way.

However, I went to my site to the @@atct_migrator and clicke don migrate. After some time, the following error was there:

I opened the document mentioned /Plone/insight/ausnahmen but could not see anything being wrong.

I also checked the topic Migration from AT to Dexterity error but could not really see, what I would have to do...

How can I find out, where the problem is and how to solve it?
I'm not a developer, have very little knowledge of all these things as eggs, archetypes, dexterity and so on: All those words are weird words to me as I just installed plone out of the box and use it as our internal Intranet with Wiki-style linking...

Thank you very much for any help: appreciate it very much! Please tell me, what other information you need from me...

Kind regards

Hi all

I just played around with mirating just some of the content at once and could migrate FileBlobs, ImageBlobs and Topic.

With Documents and Folders I have some problems. When I try to migrate the Documents, I get the following error:

Also here: How can I find out, what the problem with this Document is? When I open it in Plone, I cannot see anything being wrong :frowning:
-> I need to migrate over 350 Documents and 33 Folders...

Than kyou for your help and kind regards

Just a hint: try staying with Plone 4.3.x first, installing plone.app.contenttypes and run @@atct_migrator. If everything goes well, then migrating to Plone 5.x.

I am not migration expert, but this seems a smoother path for me. Good luck.

Hi TsungWei

Thank you for your hint!

Unfortunately that does not work: I installed plone.app.contenttypes, started Plone and then wanted to go to the @@atct_migrator-page: http://:8080/Plone/@@atct_migrator
-> That page does not exist, I only get an error message, that the page canot be found: "the page does not seem to exist"

Any idea? Did I do anything wrong? How can I check wether or not plone.app.contenttypes is installed correctly? Is there another URL I can use?

Thank you very much for any further help!

Kind regards
David

Hello

Reading the main answer in https://stackoverflow.com/questions/27788312/plone-4-3-without-archetypes:
Do I even have to migrate the content from Archetypes to Dexterity or is it happening during installaiton of the plone.app.contenttypes automatically?

I would really be glad finding a way to properly move my site to Plone 5 where I have some strange things I hope, I could solve after a proper migration of the content to dexterity...

Thank you very much and kind regards
David

@d.wiedemann Looking at the traceback the error appears to be due to the subscriber of wicked being called. You could remove wicked from the Plone 4 site before upgrading to Plone 5.
You could also simply skip the subscriber that is breaking the migration by adding a return at the beginning of the method at_handle_target_moved in /work/plone/buildout-cache/eggs/wicked-1.1.12-py2.7.egg/wicked/at/subscriber.py. Keep in mind though that changing a file in the buildout-cache without changing it back afterwards is a recipe for desaster :slight_smile:

If you really need wiki-functionality in Plone 5 you should use https://pypi.python.org/pypi/collective.simplewiki instead of the extremely outdated wicked.

Thank you for your answer!

I can live with whatever way of doing Wiki - my actual site is just completely wiki-based. Therefore I need a way to bring my actual Plone 4.3 "wicked-based wiki site" to a Plone 5 wiki site: I can live very good with using another wiki-part, that's fine with me.
-> I would rather avoid going to hack the Python scripts, as I have no knowledge in this at all...

How do I proceed properly?

  • First move content from wicked to collective.simplewiki
    -> How is this been done?
  • migrate archetype to dexterity
    -> How can I do this in Plone 4.3? Or try to do this via @@atct_migrator after Plone-upgrade?
  • Upgrade Plone 4.3.15 -> Plone 5.0.7

What would you do? Thank you for your help!

Kind regards
David

Additional data:

After reading the documentation of collective.simplewiki, I saw, that it is only supported in Plone 5.x - therefore I just made my buildout.cfg containing collective.simplewiki and upgrade to 5.0.7.

After that my Plone crashes when updating it and an error occurs, similar to the one I already had a topic here in the community-forum: Ugrade 4.3.15 -> 5.0.7 seems ok but cannot upgrade site within browser
-> @pbauer: You suggested then to add wicked to the buildout :wink:

Somehow I'm turning myself in a circle :frowning: I would be glad to finally migrate my 4.3-Plone properly to 5, but somehow whatever I try does not work. I Would very much appreciate finding somebody willing to properly help me through the whole process...

I am quite lost and have no clue of how to continue with our Intranet...

Appreciate any help and kind regards
David

PS: The error I see when I want to do Upgrade unter Plone 5.0.7 os the following:
Site Error

An error was encountered while publishing this resource.

Sorry, a site error occurred.

If the error persists please contact the site maintainer. Thank you for your patience.

Afterwards I have again to restart the Plone-service on LINUX in order to be able to go again to the URL to upgrade the Plone-site...

Hi

What can I do now in order to migrate my site from Plone 4.3.15 to Plone 5.0.7?
How can I replace wicked by collective.simplewiki?
I'm stuck here. As long as I cannot do this, I seem not to be able to continue :frowning:

Thank you for any help!

Kind regards

Hi

Ok, I tried to just include plone.app.contenttypes and collective.simplewiki and then ran buildout: This is at the moment an action which results either in a disaster or in nothing:
This time, it is a disaster: Now I cannot load Plone anymore sigh (I have a backup, therefore disaster is in regards of my intenstions of bringing my content to Dexterity/simplewiki...)

My buidlout.cfg looks as following

############################################
#
# Buildout Configuration File for Standalone Plone
# ------------------------------------------------
#
# After making changes in this configuration file,
# you should run bin/buildout to update the components.
#
# ALWAYS back up all Plone/Zope data and components
# before changing configuration.
#
# Running "bin/buildout" will update your installation,
# installing missing components as necessary.
#
# Use "bin/buildout -n" to update many components here to the newest
# available releases.
# This will update the add-on products you've added in the eggs= lines.
# This will not, however, upgrade Plone itself (or anything else you've
# pinned with a version specification). To upgrade Plone itself, see the
# comments in "Plone Component Versions".
#
# Tutorial instructions for using zc.buildout for
# configuration management are available at:
# http://plone.org/documentation/tutorial/buildout

############################################
# Plone Component Versions
# ------------------------
# This version of the Unified Installer has the components of Plone 4
# preloaded so that it can install without an Internet connection.
# If you want to update, uncomment the "http://..." line below,
# edit it to point to the current version URL, comment out the
# "versions.cfg" line and run "bin/buildout" while attached to the
# Internet. Generally, you only want to do that as part of a planned migration.
# Note that if you are updating components, you should also check the versions
# section at the end of this file, since recipes or components other than
# those of Zope and Plone may need updating at the same time.

############################################
# Ports
# -----
# Specify the port on which your Zope installation
# will listen:
http-address = 8080


# If you try to start Zope as root, it will change user id to run as
# the effective user specified here. This user id must own the var directory
# of your buildout.
effective-user = nobody


############################################
# Eggs
# ----
# Add an indented line to the eggs section for any Python
# eggs or packages you wish to include in your Plone instance.
#
eggs =
    Plone
    Pillow
    products.scrawl
    plone.app.contenttypes
    collective.simplewiki


# Optional Functionality
# ----------------------
# Uncomment the indented lines to include these add-on products.
# Documentation on all of them, along with many more products,
# is available at
# http://plone.org/products/
#
# Example products:
# * LinguaPlone provides tools for building multi-lingual sites
# * PloneFormGen provides through-the-web form building
#
#    Products.LinguaPlone==4.0.1
#    Products.PloneFormGen==1.6.0
#
# Note that versions may be specified here or in the [versions]
# section below. You should always specify versions that you know
# are compatible with the Plone release and at an acceptable
# development level.
#
# Commonly used development tools:
# Several excellent development tools are included in the develop.cfg
# buildout extension. Read it to learn how to activate these tools.


############################################
# ZCML Slugs
# ----------
# Some eggs need ZCML slugs to tell Zope to
# use them. This is increasingly rare.
zcml =
#    plone.reload


############################################
# Development Eggs
# ----------------
# You can use paster to create "development eggs" to
# develop new products/themes. Put these in the src/
# directory.
# You will also need to add the egg names in the
# eggs section above, and may also need to add them
# to the zcml section.
#
# Provide the *paths* to the eggs you are developing here:
develop =

############################################
# Debug Mode
# ----------
# Change debug-mode to "on" to run in development mode.
# This will dramatically slow Plone.
#
debug-mode = off
# Add-on developers should turn deprecation warnings on
deprecation-warnings = off
# change verbose-security to "on" for useful security errors while developing
verbose-security = off


############################################
# Backup Directory
# ----------------
# Sets the target directory for the bin/backup and bin/snapshotbackup
# commands. Default is inside this project's var directory, but ideally
# this should be on a separate volume or backup server.
#
backups-dir=${buildout:directory}/var


############################################
# Environment Variables
# ---------------------
# Some of the behavior of your Zope/Plone instances are controlled with OS
# environment variables. You may set those here in a key / value format.
# Some common settings:
#    * TZ allows you to set a time zone for systems where it's not
#      automatically available.
#    * zope_i18n_compile_mo_files allows for automatic compilation of
#      missing translation files (may slow startup).
#    * zope_i18n_allowed_languages allows you to limit the available
#      translations.
#    * PYTHON_EGG_CACHE determines where zipped python packages are unpacked
#      for use.
#    * PYTHONHASHSEED determines initial seed for hashes. "random" causes a
#      pseudo-random value is used to seed the hashes of str, bytes and datetime
#      objects.
environment-vars =
    zope_i18n_compile_mo_files true
    PYTHON_EGG_CACHE ${buildout:directory}/var/.python-eggs
    PYTHONHASHSEED random
    #    TZ US/Eastern
    #    zope_i18n_allowed_languages en es de fr


############################################
# Initial User
# ------------
# This is the user id and password that will be used to create the initial
# user id that will allow you to log in and create a Plone site. This only
# sets the initial password; it will not allow you to change an already
# existing password. If you change the admin password via the web interface,
# the one below will no longer be valid.
# If you find yourself locked out of your Zope/Python installation, you may
# add an emergency user via "bin/plonectl adduser".
user=admin:pXD0yXZS


############################################
# Parts Specification
#--------------------
# Specifies the components that should be included in the buildout.
# All the basics are in the base.cfg extension; you may add your
# own if you need them at the end of this file.
parts =
    instance
    zopepy
    zopeskel
    unifiedinstaller
    repozo
    backup

############################################
# Versions Specification
# ----------------------
# Version information supplied here will "pin" Python packages to a particular
# version number, even when you use the "newest" flag running buildout.
# Specifying versions for all packages is a good idea and can prevent
# accidental changes when you add new packages to your buildout.
# Note that versions specified here will override those specified earlier
# in the configuration, including those from the Plone and Zope version
# config files.

I included wicked in a Plone 5 site once but only to provide a class that was missing otherwise, not to use it at all.
I suggest you disable the subscriber that is originally breaking your migration. Open the file /work/plone/buildout-cache/eggs/wicked-1.1.12-py2.7.egg/wicked/at/objectevents.zcml and comment out the two subscribers (with html-style comments).
Then run the migration. Afterwards your might be able to safely uninstall wicked and then remove it form your buildout.

12

@pbauer: Thank you for your comment!

If I understand you right, you mean to comment the Subscribers before Miration from Plone 4 to Plone 5, Afterwards uncomment this, right?
What will happen with my Wiki-Content' Will it keep the Links in Wiki-Style? When and how come thie mentioned collective.simplewiki into action?

And uninstalling wicked: How will I do this? Via pip?

-> Commenting html-style means the "#"-Character in the beginning of all the lines, right?

Thank you very much and kind regards
David

Hi so the file should look the following way?

<configure xmlns="http://namespaces.zope.org/zope"
           xmlns:five="http://namespaces.zope.org/five">

<--    <subscriber						-->
<--        for="wicked.interfaces.IWickedBacklink		-->
<--             OFS.interfaces.IObjectWillBeRemovedEvent"	-->
<--        handler=".subscriber.at_handle_target_deletion"	-->
<--        />							-->
<--								-->
<--    <subscriber						-->
<--        for="wicked.interfaces.IWickedTarget			-->
<--             zope.lifecycleevent.interfaces.IObjectMovedEvent"-->
<--        handler=".subscriber.at_handle_target_moved"		-->
<--        />							-->

</configure>

-> Still have errors...

What i still don't understand: At what stage shall I do what? I have three things to do (from what I see in this topic and in the other topic I have regarding this upgrade):

  • transition wicked -> collective.simplewiki
  • transition archetypes -> dexterity
  • upgrade Plone from version 4 to 5

What order must i use and how go on? I don't see a clear path yet: Since weeks I try now any kind of possibility but never with the desired result:
Plone 5, content still being wiki-style (keeping all the wiki-style links), preferable Dexterity...

What shall I focus on now as first step: Migrate Archetype to Dexterity, migrate Wiki from wicked to simplewiki or Plone 4 to Plone 5?

Thank you and kind regards
David

Just found out: I have to enable first the Add-On in Plone 4.3.15... I can now reach the site

@hvelarde:
You are right. So far I was just usually able to solve my problems with the help of the documentation of Plone or some help from the community. Just this time, it somehow does not work out as I expected...
-> So I contacted a potential helping company in order to make me an offer...

Nevertheless, I still try - don't like to give up :wink:

So I could get to the Migrator unter Plone 4.3.15 and could migrate all my content except the Folders. There I run into the following message from the Migrator:

Thank you again for all your patience and help!

the things you're trying to accomplish depend on the status of your current site; migrating from Archetypes to Dexterity is trivial is you only have the standard content types.

upgrading from Plone 4 to Plone 5 may or may not be trivial; things can break as you may have noticed already if you follow the messages on this forum.

migrating from Wicked to collective.simplewiki is something that may have not yet been covered: contact the package maintainers, they may be willing to provide a path if you pay for the development.

I appreciate the fact that you have tried and learned a lot, but there comes a time when you have to acknowledge that you're not going to make it; the sooner you realize it the better.

I think that time is now.

Plone is powerful and complex; don't expect to master it in 2 months.

@d.wiedemann that looks like a interesting error. Since I am the author and maintainer of the migration-code in plone.app.contenttypes I am interested in figuring out if this is a issue in the migration. I'm willing to help you figure that out in a shreen-sharing session (e.g. teamviewer). Please contact me directly by via bauer@starzel.de

Generally @hvelarde is right. It can be hard doing migrations and it would be good to get professional assistance when addons come into play and ruin a otherwise clean migration-path. Not all addons provide clean unstall-code or upgrade-paths to Plone 5. That's the price of using some addons. See my talk in Brasilia https://www.youtube.com/watch?v=Sc6NkqaSjqw for more about that topic.

@hvelarde:
Thank you for being so honest - as I said, I contacted a company from your list of possible contacts (the only one available in Switzerland :wink: ) in order to let them help me with this.
-> Why I did not give up so far was just the fact, that I was thinking, that we really have an easy, not so complex site, which somehow should be able to be migrated easily. This seems not to be the case...

@pbauer:
Thank you for your offer, I already sent you a message - I appreciate your effort!

Kind regards
David

Yesterday we had a screesharing-session and figured out how to fix the issues:

Generally you should migrate to the latest Plone 5, then migrate to Dexterity. Even better to migrate to 5.1 since the at-dx migration in 5.1 included many improvments that were not backported to 4.3 or even 5.0. Another thing (not an issue here): If you have LinguaPlone you need to migrate to plone.app.multilingual (with archetypes.multilingual) before upgrading to Plone 5! Then migrate from AT to DX in Plone 5.

This is what we did:

  • Disable the wiki-behavior in Plone 4 in editing-controlpanel (to keep the brackets (()) and [] during upgrades
  • Include wicked in the 5.x buildout
  • Patch the subscriber from wicked in wicked/at/objectevents.zcml as described above to prevent it from doing anything stupid.
  • We also had to patch a event-handler of plone.app.linkintegrity (that will no longer be necessary after Plone 5.1rc2 since I added https://github.com/plone/plone.app.linkintegrity/pull/60)
  • We also patched ZCTextIndex.index_object which is bascially a good idea to do during migrations since it speeds things up a lot (no indexing of files and documents!) and you're not doing a query for SearchableText during a migration. You should rebuild the catalog after the migration.
  • In Plone 5 with dexterity with all items moved to Dexterity the brackets were still there
  • Add collective.simplewiki to the buildout and install it. The brackets are now (after a restart) turned into wiki-links. Works like a charm and ist much more lightweight than wicked.

What remains is a uninstall Step in wicked that allows you to remove wicked from the buildout without throwing AttributeError: type object 'IFieldValueSetter' has no attribute '__iro__'
