How I've done it in the past for Dovecot and Exim is to copy the root
filesystem from the server to another machine, chroot into it and then
upgrade the dovecot- and exim-related packages.

Review any config file changes in the chroot, test the config as far as
it can be done offline, and then run the upgrade on the server (with
everything backed up first, of course)

Best regards
