Ok, so I've opted to do my migration as a more gradual process rather
than stressing myself out and trying to cram it all into one operation.
Although this will end up taking longer and doesn't accomplish my
original goal right away, I think it'll be easier for everyone.
The newest production mail servers we have is Q2, which runs QMT, and is
only hosting 10 or so domains. Very little usage, and the traffic is at
about 100MB per day on average. My new plan of action is to break down
my list of domains into reasonable sized groups, which for the sake of
simplicity we'll call "migration 1", "migration 2", and so on and so
forth. I'll develop a timeline for each migration group, and coordinate
with the domain admins for those domains - providing them with dates,
changes necessary, etc. Then I'll do the process I've been doing
already, and migrate a domain at a time, but this time copy the mail and
make the necessary changes to smtproutes, dns, etc as needed.
Seems easier than doing 4,000+ users all at once, right? ;-)
One of my goals was to eventually setup some form of replication
(ideally it would be offsite, so if our main location ever went down we
could keep things going at the secondary). I've watched Jake's
"Replicated QMT" videos, and I'm watching the "QMT ISP Array" series
now. I'm trying to do a better job planning this one out, and wanted to
get some recommendations from other out there. Anyone else doing
replication? Say I setup a replicated toaster like Jake does in
"Replicated QMT"...how difficult, if even possible would it be to
convert that into something more like the "QMT ISP Array" setup down the
road?
I have a stack of unused servers, but I really want to get everything
moved from the Solaris box to a newer Linux machine ASAP, and I need to
figure out how to integrate everything in with my current setup (or
change it accordingly).
Gateway 1 & Gateway 2 -- QMT's running Spamdyke
|
SA1 & SA2 -- QMT's running SpamAssassin
|
Pop (old Solaris server) & Q2 (QMT)
Essentially that's the majority of it. So I guess what I'm asking is, is
it possible to setup a QMT, add replication, and then grow it into a
cluster? If so, what might the best approach be? Keep in mind, I'm
trying to have as little impact as possible on my users, so they aren't
having to change their settings every 5 minutes.
Thanks in advance!
