After upgrading ZCS NE 6.0.5 to 6.0.7 over a RHEL 5.5 64bits, although resources are still there, they are empty and all permissions are lost!
Don't know what is wrong, no error message that I see in logs...
At this point, I'm thinking in restoring a backup in a new VM with version 6.0.5, exporting all of the resources calendar items, and then importing them to the 6.0.7 servers using REST API for doing so.
Any ideas what could be happening? maybe there's some permissions somewhere... :S (zmfixperms -e already done).
