I am sorry, this is just confusing. With the MariaDB I just made a total backup with mysqldump --all-databases > /root/old/bck/dump_grommunio.sql
as sequence @WalterH told in another thread, only the restore is unclear to me.
With the listing of the services I can now make up a script in which first all are stopped and then started systemctl stop xxx-yyy.service
and later systemctl start xxx-yyy.service
(or if necessary with restart).
If there is a new release and I can set up a new VM with the ISO, which works and is clean, can't I simply transfer all user data from one installation to the other with commands like gromox-pff2mt
and gromox-mt2exm
or a combination of them?
The way 1-5 shown above is a ray of hope that even admins with less knowledge can do without fear of losing any data. The path is manageable and seems safe. But clear should be this one. Frankly, if the next release is available and there is no clear and safe procedure, the base is laid for a bunch of time to be spent here in the forum to clarify individual cases.
