we are using egroupware 17.1 on a Debian 10 linux i386 system with postgresql 11. We mainly use the agenda (with xmlrpc), the knowledge base, the multi language web site, and seldomly, the email interface. Please note that that system was still using Debian 9 and postgresql 9.6 until a month ago, but we plan to update to Debian 11 in a short while. The apache web site host many web sites, including the egroupware one.
The installation has been made using the opensuse hosted repository with all EPL packages.
We would like to update this installation to a more recent software version, preferably the latest one. We found that nowadays egroupware runs on docker, that it may still use apache2, that it still support postgresql 11, we found that new installations include mariaDB but may still be manually completed using postgresql, we found that postgresql 12 and later isn’t supported yet. We finally found that egroupware is only shipped for amd64 architecture, while we have an i386 one; we may enable multi architecutre on Debian, will this work?
We did not find any documentation about how to update in this scenario. Does the docker installation (simply running apt) migrates all our data into the new image? Otherwise, is there a way to load in a new installation, all our current data? Does the multilanguage web site application still work on the new egroupware?
