since some months I have a small mailserver with mailcow 0.14 running.
Now I wanted to extend this server to a bigger one and move my other domains/mailaccounts to mailcow.
But now I saw that there is a new Mailcow-Docker version.
What is the best way to move my two old Mailservers and all data to Mailcow-Docker?
In my opinion the best way is to make the new Server with a new “mail”-domain.
=> changing DNS TTL to a value like 60s.
=> prepare the settings/accounts on the new Server.
=> disable old server
=> copy each vmail/ to the new server
=> enable new server
Or is it possible to deactivate each domain and move to new server instead of the whole servers?
Is there something i forgot or where I should be careful?
Thanks in advance!
