Hello,
I’m moving all my stuff to a new server and my mailcow is the last thing left to move because I’m a little bit frightened 😉
I already moved some other docker containers and their volumes succesfully by setting up the container on the new host, starting it with docker-compose up --no-start
(also on the old host) and copying the volume-data with the same rsync commands mentioned in the Migration Guide in the mailcow documentation but with the explicit path to the volume, not the whole volume folder!
Are there any reasons to not do it the same way for the mailcow and copy all mailcow volumes explicitly instead of copying the whole /var/lib/docker/volumes
folder and erasing anything else beforehand?
