I followed the Symantec document referred to by Grant_Hall (above) - the first of his two references, which is:
Document ID: 2008031204405448
I would make one addition/notation to that document:
In steps 11 - 13, when editing the management server lists, under each priority, be sure to include the server TWICE - once by name, once by IP address.
I only included the IP address.
My clients are version 11.0.5002, and the behaviour was inconsistent - some migrated, some stayed with the old management server, and some just become "lost" and "off line".
Cheers
