We have essentially a rolling upgrade. New server added to domain, installed and verified trial copy of 11d. Upgraded old server from 10d to 11d with removal of original license keys to enable trial period. Entered upgraded 11d license keys on new server, verified backup and support of Exchange agent on old server.
So far everything ok.
Checked serial numbers on both servers in besernum.xml, both files identical.
Will we have a problem when trial period expires?
