If I get a Plone 3.0 site with NO add-ons installed: Will it be possible to upgrade to Plone 5.1 (or 5.2) directly… or will I need to do it in steps as 'normal' ?
Upgrading from Plone 3.0 to 5.x
No, in steps only. First to 3 latest, then 4 latest, then 5.
See the Plone Upgrade Guide for the different version starting with 3.
Consider also the possible switch to python3 with 5.2
I will need Mosaic, so I dont think that is an option.
Everything went OK, but I am stuck with 206 folder not migrating due to:

PS: Could not migrate them in 4.3 too
See:
I'd remove the old revisions before upgrading. You could use collective.revisionmanager for that.
Thanks a lot… that advice 'saved me'
