  • Problems with Exchange VM on ESX

    Hi guys, I'm having some issues with my Exchange 2007 VM on my old ESX 3.0.2 host which is completely at capacity in all regards, it's intermittently bluescreening and there is no discernable pattern to this behaviour.

    This just happened all of a sudden, there have been no configuration changes, no windows updates, no software updates, no driver updates since prior to the first issue, so I'm at a loss as it also can't be hardware as all other VMs on the host are fine.

    I need to put a plan of action in place as this is starting to interrupt our business operations, and we have some new as yet unused servers that we can leverage to assist (running vsphere v5.1), so what do you think my best way forward is? My current thoughts are to;
    1. Use veeam to replicate the server onto a new unused host and give it more memory/cpu etc., then perform diagnostics from there if the issue remains.
    2. Or, use an old backup VM of the server (from about a year back), replicate this onto the new server, take our production exchange server offline and copy over the virtual hdd's which hold the exchange DBs/logfiles etc. and mount them on the backup exchange copy. The configuration of exchange hasn't changed in a year, the only thing that will have changed are the databases themselves. In theory this sounds like a better option as I know the backup of the server was stable, I'm just not sure if just adding the current databases would work?


    What do you think guys? Any other suggestions? Cheers!

    I wouldn't do either.
    If the system has blue screened or generally crashed there could be damage to the database.
    Build a new Exchange server, replicate the public folders, move the mailboxes. New build (straight to Exchange 2007 SP3 with latest rollup), new databases no risk.

      Thanks, that sounds like a good idea in all honesty. Is there a way that I can set up and configure the new Exchange Server to sit alongside the current production server while I migrate mailbox to mailbox and then decommission the blue screening server, as we currently only have one Exchange server licence?

        IIRC you can install Exchange without a license key, then must add the key within 120 days - decommission the original server first and re-use the key

        (Note this may not be accurate for 2007 and should be checked)

          Exchange 2007 and higher always installs in an eval mode to begin with, so no problems with licencing.

            Re: Problems with Exchange VM on ESX

            Thanks guys, I'm in the process of making a new Server 2008 for the new Exchange install. I actually found an extra licence we have for Exchange 2007 for an old remote site office that is decommissioned now, so happy days.

            My question now is; is there a way to configure the two servers to sit side-by-side while I transfer all the mailboxes to the new server, so that during the process if the failing server goes down for whatever reason, the clients will still have access to the mailboxes sitting on the new server?

            I'd also like to do this without having to re-configure all the Outlook clients in my organisation if at all possible as they all point to the host name (or IP) of the failing server, but I'm really not sure how to go about this.

            Any advice muchly appreciated!

            Thanks guys

              With Exchange 2007 it is complex to do. It also requires Enterprise edition of both Windows and Exchange.

              As long as both servers are available, when you move the mailbox to the new server Outlook will be redirected automatically.
