Migrate from CMS docker version 2.3.8 to 3.1.2 doesn’t keep your data? There are No available topics, docs, manuals, blog chats , nothing that might explain how to do it. Only points into something with a few words selected by release and that’s it?
I have moved and installed latest version, which includes new features. Probably moving and copying files from older installation won’t just work well or even not work at all. MySQL db tables should have probably changed (from 5.6 to 5.7 plus new table structures or schemas due to new features).
I still do have running MySQL 5.6 docker image, older docker install was kept at the original location, new install with new directory , so how can I migrate all the contents (display info, profiles , library images , campaigns , etc etc and load then into the new version ?
