You might want to give this article a read if you’re upgrading XenServer to Feature Pack 1. We haven’t experienced any errors during our testing with clean installs of XenServer FP1 and Provisioning Server 5.6.

The virtual desktops are using local storage so my plan was to backup the virtual desktops over the holiday weekend and import the virtual machines this week.

The release notes mentioned the following regarding lro and gro:

I’m restoring 5.6. I’ll upgrade when/if Citrix posts a fix.
Citrix released Provisioning Server 5.6 SP1 on Oct. 22, 2010.
The release notes contain instructions for streaming XenServer hosts. Hasta la vista, Altiris? Probably not…
