Hi,

SBS 2008 Premium. Exchange 2007.

I've read quite a few old posts on here about the steps involved changing
from one static IP address to another. From this information I have the
following steps planned:

1) Backup
2) Before shutting down my server I plan to log onto my web hosts control
panel and change the A record from the old static IP address to one of the
new 5 static IP addresses I have with my new line. I wont need to alter my MX
record as it just points to mail.domain.co.uk?
3) Power down server, move it to the new office and power up.
4) Re-run the CEICW wizard

Does that sound OK? Any suggestions / pointers?

If I do the above, what will happen to emails in the hour or so it takes me
to move the server?

Regards

Sounds fine to me - change the "mail" A record to the new IP address and
also don't forget the rDNS record for that new IP address!

For email, you might want to look at getting a backup MX:

http://www.dyndns.com/services/mailhop/backupmx.html
http://www.zoneedit.com/

The sending SMTP servers will likely try to resend the mail if your
server is down, but the retry periods are all different - from a few
days to a few hours.

Hi James,

Thanks for the reply.

I looked into a backup service for my emails a few months ago but I wasn't
getting anywhere. I was probably asking the wrong questions / looking in the
wrong place. Anyway, I've created a DynDNS account and setup a backupmx
entry. $40 (£30) for a years piece-of-mind, bargain if you ask me!

I've never been 100% confident my PTR records were correct but everything is
working, as far as I know! I believe you have to get your ISP to create /
alter PTR records? Asking British Telecom to do this would be interesting to
say the least..

thanks again.

One particular thing of note that I didn't see mentioned is the TTL of the
current A record. Although you can move in an hour, the old record could
exist on servers for much longer.

What I recommend doing is changing the TTL for the existing record down to
30 minutes. Make this change *at least* as far out as the existing TTL is.
So if the existing TTL is 3 days, make the change 3 days before you plan to
move the server. This will ensure that every DNS server that caches you're
a record will expire it quickly and that any that cached it with the 3-day
value will have already expired it.

Then, on the day of the move, follow your process outlined.

Then, after testing verifies everything is up, you can bump the TTL back up
to a longer-term maintainable value.

IF you do this, I actually *don't* recommend backup MX services. Many people
love 'em. And that's fine, it certainly won't hurt, but for me, a legitimate
sending server will try to resend the message every few hours until
successful, and will generate delay and fail messages at predetermined
times. For me, that is actually a *good* thing. The sender knows that
their message has not been delivered so they aren't wondering why I haven't
replied yet. With backup MX, the message is delivered "successfully" so the
sender gets the appearance that there are no problems or delays, when this
is actually not the case.

Matter of opinion, that last bit....

-Cliff

James> Thanks for the tip with BT - I'll do that right now!

Cliff> I totally see your point of view. I guess there is no clear right and
wrong with this, just what works best for each scenario. Thanks for the
advice with regards to the TTL I'll also do that now.
