Should I be okay to upgrade to DevEx 6.2, or will this cause problems with the inherited controls since they are compiled with 6.1.5?

I can't recompile because I am now using the new dll's you guys had for the training.  I recompiled my BO's to work with the new stuff and don't want to go backwards now.  So am I just stuck waiting for the new StrataFrame release until I can use the new DevExpress release?  If so, that's fine...just wanted to make sure there wasn't some other way around it.
