migrate ejb timers

Hi,
I am confused about "migrate ejb timers" option of glassfish.
"migrate ejb timers" is configured per cluster instead of per instance. And only from one source instance to one destination instance or to a set of destination instances(if left empty).

Assume that i have a cluster configuration consisting of instance1, instance2, instance3... instanceN

Assume I selected instance1 as "source Instance" and left blank "destination instance" so that if instance1 fails, timer on it will migrate to one of another instances who are currently running.

Question 1) Say the scenario happened timer migrated to instance2. What will happen if instance2 goes down? There is no "migrate ejb timers" configuration for it in the cluster?

Question 2) At console, at "migrate ejb timers" page, when I select one source instance although I have more than 1 destination instance running I can't left destinationInstance option left (?). However it says "If empty, one alive server is picked randomly from the cluster" below.
