xenserver with sancopy

Hi,

We are using sancopy to migrate data from CX4 to VNX.   It is pretty straight forward process basically we are doing sancopy push.   For Xenserver, is there any step or thing that the system administrator need to take care.   For other server like AIX we know we need to vary off the vg and shutdown the server during cutover.   For Xenserver, this is the only platform that I don't find much information.
