<shudder> I've done at least 40 2003 -> 2007 upgrades. Several dozens. As Rick says, and as I say - don't do it that way! You are causing yourself pain. Regards, Michael B.

Wait, you mean fail? That's not how a move mailbox works. The move is a copy -> delete function, not a delete ->move. So in the event a move of a mailbox should fail, it reverts back to the original server, and you can clean it up and try again. Users are none the wiser. So you start moving mailboxes. Outlook automatically detects the move the next time the user starts up, and no need to touch desktops or modify clients. If a move fails, Outlook still sees it on the old server. There's no halfway functional server at all - even if some moves fail, both servers are fully functional. Also, renaming the server to the old server name is more likely to cause problems than solve them - what's the planned process? backup data retire server clear AD of Exchnge, including hacking your way through ADSIEdit Install new server with old server name restore data Hope the identical host name doesn't have any sort of other odd problems, such as GUIDs and AD records...? And so, assuming the process I just outlined (may have missed a step, but at the high level, I think it's about right) how is this less risky than a move mailbox approach? Oh yes, and there is no renaming the Exchange server after the server has been restored - once Exchange is installed, that server name is what you named it originally, it isn't renamed. There is no rename process. So, just to be clear, if your consultant is recommending this approach, I suggest a new consultant. Michael has recommended a smooth, pain-free solution, I've done the same (and I've done more than a few migrations, I can't speak for Michael's migration experience but his knowledge is top shelf) and your consultant has (presumably) recommended a path that is unsupported, difficult, and likely to fail. Sorry to sound blunt, but the approach you appear to be headed down is the definition of risky. On Thu, Sep 4, 2008 at 9:04 PM, John Parker <jp@xxxxxxxxxxxxxx> wrote: My Question is this. Why is it risky? We intend to rename the server afterwards to the old server name once the mailboxes are on the new box. Why is this risky since it leaves the old server intact. Whereas, if the move mailboxes bail, I have a halfway functional server. And am forced to do a restore. The old server has been somewhat unstable and I do not want to take a chance with losing data. _____ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Rick Boza Sent: Thursday, September 04, 2008 7:43 PM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Exchange 2003 to 2007 Via backup Exec Could not agree more - this sounds like a much more riskly approach as well as potential for significant user impact. Best method nearly all the time is to move the mailboxes and avoid pain for both the users AND for you. On Thu, Sep 4, 2008 at 7:42 PM, Michael B.

We currently have a 2003 server standard running exchange 2003 Enterprise. It is on it's last leg and we are replacing it. We are getting our new server in tomorrow. I will be installing Server 2008 64bit and Exchange 2007 Std. Once all of this is installed I intend to restore the individual exchange 2003 mailboxes to the 2007 machine from backup exec 11d. Also, to make things go faster, I am also running the backup to disk using a backup to disk folder I created. my consultant sources say that this will work. So... My intention is to shut down the smtp service and then perform a backup. Once Backup is complete, then I assume that I install a Backup exec agent on the 2007 box and then restore the individual mail boxes. I am also assuming that I will need to go to the new server afterwards and reconnect the mail boxes? Or can I use the "Recreate user accounts and mailboxes" feature within Backup Exec? Am I correct in this ideology? Thank you for your help in this.
