At the Plonator sprint in Munich we migrated https://www.plone.de from Plone 4.3 to 5.2
Many years ago it had started on Plone 3 with flurries of community-activity but was rather inactive lately.
- We upgraded the Site to Plone 5.2.1 and migrated the Database from Python 2.7 to Python 3.8. The migration-code can be found here: https://github.com/collective/plonesite.de/blob/master/src/plonede.policy/plonede/policy/upgrades.py. Again we used https://github.com/collective/collective.migrationhelpers for most of the code.
- We trimmed the content down a lot and created a single-page-ish frontpage with information that is mostly tailored for marketing, rather than community.
- We created a new theme based on https://github.com/collective/plonetheme.tokyo
Thanks to the sprinters: Stefan Antonelli, Robert Kuzma, Max Jakob, Philip Bauer und Steffen Lindner
