[exceprts from mail Derek sent to sipb-afsreq]
1) We send out mail telling people that on such-and-such a date we
plan to move our database servers to these addresses:
18.181.0.22
18.181.0.23
(or whatever)
2) On that date, we *do* move the servers to those addresses, and
start advertising *only* the 18.181 addresses, however we also leave
one of 18.70.0.21{0,9} active as a DB server, so that sites that are
slow in updating don't lose totally.
3) After about 2-4 weeks, we bring down the 18.70 machine, and let
people who haven't changed by *then* lose.
If people do not think this is reasonable, speak up now or forever
hold your peace!
-derek (a person who thinks changing the IP addresses of DB servers is
a *BAD IDEA*)
This fits in reasonably with what I recall of the server migration
outline. Anyone else see any problems?
