We are going to physically move our boxes, but for the dns the process will amount to the same thing.So here is what we'll do: - Lower the ttl on all zones three days before the move
Lower the TTL on all zones OR INDIVIDUAL A RECORDS at least [OLD TTL] before the move...just worth clarifying.
- Move all the boxes except for one dns server
My opinion is don't move the DNS servers at the same time as the other servers, or as an alternative, make your delegation changes either after the move or more than the TLD's TTL before the move (i.e. for .com, more than two days before the move).
