I have been asked to (maybe) re-theme a Plone 4 site.
I would prefer to upgrade it to since theming in Plone 5 is easier.
The main problem is that the site has hundreds of Location objects (Products.Maps). I assume these needs to be migrated to something else.
Is this 'doable' in a sane way? Would it be possible to use /@@custom_migration to map the fields to another content type . Maybe using collective.geo ?
Any suggestions welcome.
