okay, it's been awhile since I popped in so Hello Till and others! I'm looking at updating my 3.2.7p1 to 3.2.10p1 on Ubuntu 20.04 multiserver (7) Is there anything I need to watch out for? Only thing that's in production is panel,ns's Plan is to upgrade all 7, implement dkim etc. I need to move various users email folders to new mx's from an old postfix/squirrel server. Any input greatly appreciated! TIA Jim..
One thing to watch out for is not reading "How to Update ISPConfig 3". Have you already read it? Is that squirrel server the ISPConfig you are upgrading? For moving mailboxes there are previous threads in this forum. Easy but maybe more work is imapsync by Giles Lamiral: https://imapsync.lamiral.info/
More than once, gotta go thru again and do some copy/paste (hate making typos). It did leave questions about the slave aspect of it and noted to do backups before begining. it's an old single server ISPConfig 3.1.13 (time to retire this energy hog) only half a dozen maiboxes to move across Looks like a whole lot of stuff to be installed but doable, more reading to do and hopefully stumble upon a qwk and easy way to move 1 domain/mailbox at a time Tks for qwk responce
Which kind of setup does the old system use to store emails? If it uses Maildir like ISPConfig is doing it, then you can just copy over the whole maildirs e.g. using rsync or scp after creating the mailbox on the new ISPConfig system.
The new system will use Dovecot, but the old system may be using either Dovecot or Courier as IMAP server. The IMAP folder path is slightly different between Courier and Dovecot. The path of a mailbox like /var/vmail/domain.tld/user/ on Courier servers becomes /var/vmail/domain.tld/user/Maildir/ on Dovecot systems.
