(1) if you are on x86 hardware, and especially if you are using more than 4GB of RAM today, it might be time to make “move to modern hardware” one of your essential upgrade steps. SQL Server 2012 will no longer support AWE, so this means that no matter what edition you’re using and what your boot settings are, SQL Server will only be able to see 4GB of RAM. Obviously this can have quite a dramatic impact on your workload if you’re not expecting it.

(2) if you are on SQL Server 2000, you will need to upgrade in multiple steps, since a direct upgrade path to SQL Server 2012 will not be supported (regardless if your plan is to upgrade in-place, or side-by-side using backup/restore, log shipping, detach/attach, what have you). You will need to either (a) upgrade the 2000 instance to 2005, 2008 or 2008 R2 or (b) first backup/restore or attach/detach from 2000 to 2005, 2008 or 2008 R2. Only then will you be able to proceed with your normal upgrade/migration plans.
