We're currently running a XenServer 5.0 pool with 3 Hosts. I'd like to upgrade this to 5.5, but am wary to jump right in, so-to-speak.
Wondering if anyone has attempted this in their own environment?
I've upgraded one four member pool from XenServer 5.0 to 5.5 in-place. I've yet to discover any issues directly related to the upgrade or new version.
The big feature for me was the AD integration and it works perfectly.
Let me know if you'd like any specific information, I'd be happy to oblige.
