We've got multiple XenServer installations/pools and have started upgrading them to XenServer 6. We haven't seen any issues as of yet - have you found anything to look out for?
Yes is pretty straight forward , just boot from the installer CD and restore the backup of 5.6 when prompted.All the usual rules apply, upgrade pool master first, take backups of the VMs before starting the backup (or wing it) etc.
They've all been upgraded now. Was painless.. Had to set up a licensing server for 6.0 but that was the only caveat. We keep it offline until its needed.
