I've read through the FAQs about Migrating Smartermail and think I understand it. I have one question though:
We are migrating a 13.x version of SM with about 6 domains to a 15.x SM that already has 1 domain in operation. The 15.x target server isn't a brand new clean installation - we already have mail that is coming and going here.
This is my first migration and it appears that that standard migration is to stop the SM servers, copy a bunch of folders/XML files over, and restart. But, will this work if we already have domains, users, filters, aliases in the target server? We don't want to end up overwriting anything.
Any suggestions would be appreciated.
