You might want to do something to double-check that you're actually interacting with the new server rather than the old one (for example make some edits, then switch back to the old server and confirm you don't see them there). But correct, you shouldn't see complaints about the SSL certificate--the same one is installed on both old and new servers and your browser validates it based on the hostname you've entered, not based on any particular IP address.
How long should we plan for the outage to be? 2-3 hours or less?
Having run through it once myself already, it should be doable in under 30 minutes (most of that time is spent waiting for the database dump, file transfer, import and search reindexing). -- Jeremy Stanley
