Windows Server 2003 R2 to Server 2008 R2??

I have a fairly new server that was installed with Server 2003 R2 (64 bit). This was done before my time here. I am in the process of making changes where that server resides and wanted to upgrade it to Server 2008 R2 (64 bit).
Since 64 bit was installed previously, can I just upgrade the server to 2008 O/S?
I do not want to do a complete wipe and reinstall here. I am looking for any hidden gotchas before I undertake this. Better to ask the experts first...

You need to ensure what is running on 2003 R2 would run fine on 2008 R2.

You also need to ensure the edition of 2003 R2 is upgradable to 2008 R2, otherwise it should be fine.

The following shows you the upgrade paths:

Of course 64 bit can only upgrade to 64 bit OS. You can't have a cross platform upgrade.

One possible gotchya: if you currently host TS clients you may need to re-activate for RDS.

The upgrade scenario (X64 to X64) is supported, as the previous experts have already commented.

Without knowing more about the hardware or software roles of the current server, its tough to say more. Be sure to read the additional articles about the Known Issues When Upgrading and the Application Considerations. These are very important during upgrades.

Be sure to reach out to any software vendors for upgrades to any software or hardware\firmware currently running on your server. You may have to re-install software in a compatibility mode, if the software does not include an upgrade path for 2008 compatibility.

I think most admins would recommend a clean install of 2008 if possible, but given your hesitance to do this, best of luck with the upgrade.
