Upgrade to UFT 12?

Curious if anyone has tried this yet. I am working on convincing upper management the need to upgrade from QTP 11 to UFT 12.

I know it is only a few days old now, but has anyone tried the new UFT 12 installation? Anyone try upgrading from QTP 11 to either 11.53 or better yet 12?

I don't want to lose my framework and script, and really need them to continue to run the nightly tests after the upgrade.

So - what is the good and the bad and anything to watch for.

Thanks,

Jamie
