moving network

[Tony]

I have a small network.
2 AD, 1 Exchange, 1 internal dns servers and 2 external dns servers and 10
users.
We are moving our office to another location. Our isp is giving us another
IP range
for our internet connections.

To minimize downtime on our emails, what are best options?
1) should I shorten the ttl in external dns servers to point to new IP
during move?
the move will be 3 hours of downtime?

2) should I setup another SMTP server and add a second MX record to
my external dns servers so emails being queued?
if this is feasible, do i need to add accounts to SMTP servers so emails
won't get bounced
back?

3) any other alternative and better way?

TIA
Tony

Figuring it would take a day or so for the change, a day prior to the move,
alter the MX record. If you will be changing TTLs, do that a week prior to
the move. Hopefully any cached records will have expired in the interim.
Honestly, its better to do this on a Friday afternoon so when everyone comes
in Monday, its all working.

Thanks Ace,

If I alter the MX record to point to the new IP
on friday afternoon, and if I move the servers
to the new location, you are saying the
change would should take effect on saturday or
so?
