Turns out there are XenApp 6.5 features that are not available in XenDesktop 7, XenApp edition. Make sure your environment isn't dependent on some of these features. http://www.shaunritchie.co.uk/xenapp-6-5-vs-xendesktop-7-app-edition for a great table describing the differences.

Rapid vCenter Database growth

I ran into the following issue with a vCenter database. The DB had grown 25GB within a week. The vpx_event and vpx_even_arg tables were the primary growth contributors. When reviewing the Events side of the Tasks & Events tab in the vCenter console, there were a very high volume of logon and logoff events (3 per second). These events were all being created by a single antivirus scan VM, which was then rebuilt. After resolving the source of events, the database growth went negative.
