    Upgrading from 2003R2 .. Upgrade or Backup and Clean Install?

    Good afternoon ..

    So, the plans are all coming together for the summer upgrades programme here at my school (just me, 2 x 2003R2 servers, 80ish XP Pro machines, licenses for 2008R2 and Windows 7 Pro as well as Office 2010 and many other bits of stuff) and by the end of the summer I plan to have 2 x 2008R2 Servers, 80ish W7Pro Machines with all the relevant software installed ..

    Now, looking at the GPO structure in my VM version of 2008, it all looks good, my question is upgrading the servers from 2003R2 to 2008R2 .. is it just good to upgrade them directly with the disks and stuff, or should I do clean installs and start again?

    Of course, either way, there will be backups galore, but just looking for any horror stories and trips I should be aware of in the process if I go for a direct upgrade ..

    Cheers all!

    Are your 2003 R2 servers 32 or 64 bit?

    I would do a clean install, which may be your only option anyway if the current servers are on 32-bit 2003 R2.

    Oh, forgot to say, if both are DC's. demote one, install new OS on that one and promote, then demote the other and do that one.
    If only 1 DC, do the other server first and make that a DC, let it sync and then demote the other one.

    They are running the 32 Bit 2003R2 but are 64 Bit compatible .. I just took over the setup basically hence moving it on ..

    I think the idea of demoting - upgrading - promoting is the best (they are both DC) as that way the settings will move over and it saves setting back up the 175 users or so .. which I know isn't a lot, but when there's only lil old me .. lol ..

    I'd go clean install every time, upgrading (albeit server or workstation) has always left me with operating systems with issues.

    You can't do an inplace upgrade from 2003 32bit to 2008 64bit.

    I know what you mean, just thought I'd ask the question in case I got a mass of "it's a joy to upgrade and no problems" but didn't expect that, it being Microsoft who's idea of an upgrade is to replace all the bugs they've fixed with new ones they need to fix .. lol ..

    I've found Server 2000 to 2003 goes okay as an upgrade, but as stated to 32bit to 64bit will need a fresh install. If you need something to fall back on, just create a VM on a PC which can run as a 2003 DC for now.
