multi-gigabyte mailboxes, OK, but empties, on RTM? Quite surprising to me
too (both parts)

Something new to test and look out for. Don't remember this bugged (or
whatever) in connect.

Yeah, no forklift. Sigh. What you have to do is bring both versions

one to the other. The process is S L O W. On a large SBS, with large
mailboxes, I'm guessing we're talking days not hours. Even
essentially new empty mailboxes were hours.

Hours??? !! Yikes. Were these done with the GUI or the shell?

If you have more to do consider trying this;

----
Move Mailbox wizard that you run from within the Exchange Management
Console is multi-threaded but is limited to a maximum of 4 threads.
You can increase this number if you use the Exchange Management
Shell to move mailboxes. The specific parameter that you need to use
is the -MaxThreads parameter, which has a maximum value of 30.
However, before you go about setting this parameter to the maximum
value of 30, consider where your bottleneck will be if you do this
and therefore whether you will really benefit. It may just be that,
after testing in your environment, you really do not benefit from a
performance perspective from setting the -MaxThreads parameter to more
than, say, 10.

yeah Jim, if moving from 2003 to 2008 via a tempDC I would also
keep the tempDC at 2003, I see no reason to affect the originAD in
order to accomodate a 2008 DC, the targetAD can be adjusted while
at 2003 level, on the tempDC, to allow SBS 2008 to be
incorporated, but at this time it would be disconnected from
originAD and have references removed about originSBS.

SO, it seems you guys are telling me I can't 'forklift' a store
from Exch03 to Exch08. BUMMER (if true), how do they handle
'inplace upgrade' of Exch? or is that also 'not supported'.
(not much Exch08fu in this grasshopper)

I don't really see much problem in using an RSG as an interim step.
Creation, and subsequent removal, of an RSG is simple in Exch03,
does Exch08 make it more difficult?

You know better as I have not suffered this yet. Introducing the
recovery storage group might be more fun than one wants?

Well, no, you could use an SBS 2k3 tempdc. In fact, I'd prefer
it. You'd have to move the Exchange using a recovery group
mount, but that should be
doable.

And it requires a 64 bit, 4 gig ram minimum temporary machine.
Granted that box is only $600 if you do not happen to have a
modern box that will take 4 gigs of ram. Any new decent
workstation should be 64 bit and take some more ram and a new
temporary hard drive. On Sun, 21 Sep 2008 22:20:37 -0700,

You're going to have to have someplace to park the current
domain and exchange. A swing to a temporary box and then
flatten your original and install back on it would work, but
it's a lot trickier here since you can't
do a simple move of the Exchange files. You have to move the
individual mailboxes while you have both versions of Exchange
up and running. And it
will be slow. Really slow.

I've read through the 2008 migration installation CHM file,
and that sounds terrific if you have a new server available,
but what about the
situation where you want to put 2008 on the same box as 2003?
I'm not
speaking of an upgrade, which I know isn't supported because
of the move
to 64-bits, but a separate clean installation of 2008 on
another partition
which could utilize some form of earlier export from 2003 (AD,
settings,
etc) that could be imported into 2008? I realize this is far
from ideal,
but I was wondering if there was a means for doing it.

Let's assume in this case that the box meets specs (enough
RAM, 64-bit
CPU).

Thanks
