Upgrading from 9.2 to QC ALM 11.5 patch 2

Hi everyone,

We are getting ready to upgrade from 9.2 to QC ALM 11.5.   Has anyone gone through this particular upgrade?  Is there anything I need to be aware of?   Any gotchas or issues with the upgrade?  Is there anything in particular that woudl make the upgrade a smooth one?

Also has anyone come across any bugs in 11.5 since their upgrade?  

Your help is appreciated.
