I've been looking at an upgrade to my SQL Server 2005 Enterprise edition. I'm specifically looking to upgrade as I'm hitting the limit of my 2 CPUs at the moment. It looks like I could move to 64 bit Standard at my hosting provider for about the same I'm paying now. I was going to try adding another 2 CPUs to the set up but figured I could at least try out the 64bit Standard edition first and then add the additional CPUs if it wasn't already improved enough.
Is there anything I need to look out for with moving to a 64 bit platform? ie are there any gotchas with this migration? Looking at the feature comparison listed here I don't think I'll miss anything from the Enterprise edition. I'm not sure what Parallel Index Operations are but a little google for that string seemed to suggest it was just something to do with rebuilding indexes whilst the db is running, something I don't need to do. Is there anything not listed at that link I should be aware of?
