Possible, but it sounds like a lot of work. What I did for my recent
mail-server migration was:
- set up newbox to do oldbox's job;
- point MX records to newbox (which will take time to propagate, of
course);
- set up on oldbox:
relay_domains = all the things that used to be local_domains
local_domains = localhost (for debugging)
