You can just rsync everything over to new system.
I did a few initial rsyncs some time ago. So a new rsync will be relatively quick. There's 25GB of data and over a million files in the copy on the new server, which is probably a few months out of date compared to the online server. The online machine is very slow and I hate asking it to calculate anything, so I don't know how much data is left to sync.
If the recommendation is to rsync everything and not exclude certain files, then I would like to ensure that dovecot rebuilds as much of its data as I can. Are there some doveadm commands I should run on the new server after the rsync and before I bring it fully online? I am OK with having a few hours of downtime if it would help dovecot make sure things are really clean.
At this time, I have not deployed Solr as the search engine for dovecot, but as I am heavily involved with that community, I probably should. If there are any guides about switching an existing setup over to Solr, please point me at them.
