You're on track Roger, migration is triggered by lowering the threshold,
then resetting it to its original higher level (in my case 95%). One
suggestion, don't lower it to 0%. I did this to trigger migration and found
if a client is backing up when migration triggers, the migration never ended
until the client backup finished. 1% allowed the migration to finish, then
the client backup continued until finished. Hope this helps you.
