You don't have to upgrade all the files in the Vault in bulk. For example, Check Out and Open a 2010 file in 2011 SolidWorks. Notice the yellow warning icon on the Save button. It's just telling you that as soon as you Save the file, it will a 2011 file. Just wanted to say it's optional.
Thanks for the answer, just want to clearify so if I open an older version of an assembly and then resave it as a 2011 file. Will anything happen to the relationship between parts files that resided in the assembly seems they are still at 2010.
Usually it is better to upgrade all files if you can. We experienced some issue in the past. Users don't pay attention to save the file first, start to work and some new functionality does not seems to work as expected. We had such problems when we upgrade to 08 from 07.There is an application File version upgrade.exe on Support folder on installation kit.

I like Save All
I've never seen an issue because Bulk Update wasn't performed. If there was an issue, why isn't mandatory?
New to this SOlidworks/EPDM environment but am always willing to offer some advice if I can. We too will be going through the update stage from 2010 - 2011 and I personally think updating all the files to 2011 is the best way as you know its done and your not leaving it up to the users to do. I was thinking about using the file upgrade tool to do the whole lot - has anyone had any issues with this?
Again from my understanding you dont have to upgrade the whole lot - but surely it makes sense to do so????
