If you are still running Outlook 2003 as long as you leave the old empty server running for a while it will update outlook profiles as they logon to email as well to point to the new server.
    We're running Office 2007, with a view to goto 2010
    If I installed EX 2010 as a VM, can i leave the mailboxes alone until I turn it back to a physical machine (the mailboxes would then be on the same server as the physical 2010 install)?

    I think that Outlook 2007 has an autodetect feature that will just find the right server anyway. I think what you are talking about is a swing migration, moving all the users off the original server then upgrading it with fresh OS and Exchange and putting them all back to retain the same name. This would work fine but you will need to move the users and their mailboxes to the new system before putting them back so that they can be properly upgraded to the new structure. I would do this kind of thing over a weekend and so load would not really be that much of a concern.

    At any rate the store on the server at the moment is in a 2007 format so will need to be moved to a 2010 based install at some point to be compatible. If you are concerned about space perhaps you could put in a desktop drive into your virtual server to stage the boxes onto temporarily while you reinstall the exchange metal. You could also look at putting it on to a powerful workstation if you have one around. With no clients you could probably get away with putting it on a Core2 Duo 2.8GHz with 4GB of RAM (just scavenge from another workstation temporarily to up the ram if needed). That may be another option other than going with a VM.

    thanks synack - the mailbox drive is sitting at about 70Gb so will try and copy them to an ext HDD and do the spare server/pc idea..

    Yes it's to be a physical so that sounds relatively simple (I may regret having said that, time will tell). So it's a case of re-housing them as it were. Not really looking forward to it but it will have to be done. Thanks Synack.

    Ok I have installed 2010 onto a midway server and just waiting on exchange 2007 to finish installing updates
    Quick look through the EMC on 2010 shows that it has found all the accounts, etc and all seems ok there, so just need to migrate a few test mailboxes over to 2010
    Once everything has been migrated to the new 2010 server (EX02) I plan to shift it back to its main server EX01 (Currently 2007)

    Do I need to move them onto a mailbox store on EX02?
    Is there anything eles that I need to migrate besides mailboxes? Specifically my SSL Certificate!

    EX01 is currently on Server 2008 x64 - can i just upgrade it to R2, remove 2007 and install 2010 then shift the mailboxes back over from EX02?

    You will need to move them onto a store on the EX02 box as you will need to remove all of the EX01 2007 services in order to put 2010 on, I'm not sure on the cert as it may migrate accross automagicly but it will probably need to be transfered manually. You will also need to transfer any public folders if you have them to the new server manually especially if you have previously migrated up from Exchange 2003. You may also need to transfer the send connectors and OAB roles over too. This may be of help How to Remove the First Exchange 2007 Server in a Coexistence Scenario: Exchange 2007 Help
    Microsoft Exchange 2007 Training Clips

    You can upgrade from 2008 to R2 Windows Server 2008 R2 Upgrade Paths but will get a much cleaner and faster machine if you reinstall it from scratch, it may seem like more work but if you get any random little anomolies during the upgrade that can take way longer. Whichever way you choose it will just be a case of shifiting those mailboxes and possibly roles/certs back over when your OS is ready for it.

    Hurray! All mailboxes successfully transferred from the Ex07 Server to Ex2010

    Now, Is there anything else I need to do to the Ex07 server before removing 2007 and installing 2010?
    Its running Windows 2008 x64 - does it need to be R2?
    What happens with to the settings / configs such as send/receive connectors, outgoing rules, etc.. where are they stored and will they be there wehn 2010 is installed?

    Ok this is getting confusing..
    Too many "servers" lol

    So, I have an existing 2007 org (Server1).. I have installed 2010 on a new server (Server2) and migrated all the mailboxes over to Server2
    I am now in a co-existance environment

    Outlook is working correctly and connecting to Server2

    I need to remove 2007 and install 2010 on the same server (Server1)

    What I'm confused about is how to transfer the necessary 2007 roles, etc to Server2 before removing 2007.

    We're looking at doing this soon as well.

    I've had a play with Exch 2010 at home, and the basic config isn't hard at all. My only concern is migration 1500 mail boxes over - especially when some are running into the gigs of data.

    If anyone has actually done this, has MS provided us with a streamlined, stress free migration path?

    OK think I'm starting to get somewhere...

    Looks like all the necessary roles are auto-updated when 2010 is installed so only need to move Mailboxes (done) and the OAB (now done)

    Whats confusing now is references for the need to leave 2007 inplace for a while because when users first open outlook it goes to the 2007 server, which then redirects them to 2010...
    I need to get 2010 onto the primary server (currently 2007) as the current server (really just a PC) is slowing to a crawl, also OWA isn't working (it could be but my SSL Cert isnt configured for Server2...)

    DO I need to do this or can 2007 be removed now?

    You can remove the exchange 2007 one now as long as all of the connectors, routing group masters, public folders and OAB stuff is on the EX02 box. As long as all the roles are transfered to the new box the worst that will happen is that users who have not logged in after their mailboxes were migrated will not be able to log on to outlook as it will look to the wrong server and not auto redirect. As this move is a precursor to putting it all back under the old name anyway that won't matter. You will want to leave the temp box running for a little while after you migrate back to direct user profiles back to the proper server though.

    You can force a rewrite of the profiles server location if required by using a PRF file to update any clients that are tardy with their logons Apply an Outlook Profile (PRF) File to configure Outlook profiles

    Thanks Synack - just moving a few mailboxes that were missed (had to trim the pupil journal mailbox down a bit :-S)
    Once they are over I'll remove 2007 cos 2010 is killing this temp server!
