Unity Connection 8.6(2) to 8.6(2a) upgrade failed

OK, so I upgraded from CUCM 8.6(2) to CUCM 8.6(2a) tonight.  No problems.  Tried doing the same thing with UCXN, but failed with the following entries in the log:


10/11/2011 19:32:43 upgrade_manager.sh|Check if the upgrade is allowed|

For information on supported servers, see the applicable version of the "connection" Supported Platforms List at http://www.cisco.com/en/US/products/ps6509/products_data_sheets_list.html|

Seems weird that the hardware is supported for the upgrade, but not for the "connection" deployment.  Can someone explain that to me?

Also, I always use VMware Workstation 7 running on Windows 7 64-bit in my lab.  I tried bumping up the RAM for this VM from 2GB to 4GB, but got the same error.  I saw some NetPro posts about increasing the hard drive size, but I think that was on ESXi and you needed a rescue CD.  I remembered that after I installed 8.6(2), I had changed the number of cores per processor from 1 to 2.

I powered off the VM, then set the number of cores per processor to 1.  I powered the VM back up, ran the upgrade again and it worked just fine.

I know its not supported, but it is interesting that I want to give more CPU power to the VM, but in doing that, it is supported?  Oh well.  I'm running 8.6(2a) on both CUCM and UCXN now.
