ASM Violation: Modified ASM Cookie after moving virtual server

We are in the process of migrating off of our 3600's to Viprion's. In this process we also have moved from v10.2.3 (3600's) to v11.2 (Viprion).

 

 

I have moved several virtual servers with no issues, although they have very low traffic. One higher volume virtual server was moved and afterwards we started getting ASM blocking pages from the Modified ASM Cookie violation. I suspect this has do with the hash the cookie uses either between hardware or between versions. I have temporarily disabled blocking on that violation, but I need to know how to address this so I can re-able it. Any ideas?
