What is the recommended procedure for upgrading drbd without the interruption
of the H-A cluster?

I have a heartbeat-based H-A cluster with some shared state on a drbd volume.
The system was Fedora 5 with 2.6.18 kernel and drbd-8.0pre4. I have upgraded
the secondary node to Fedora 7 and compiled drbd-8.0.3 module. However,
after "drbdadm up all" on the secondary node it complains that the protocol
version on one side is 82, while on the other side it is 86.

Is it possible to upgrade drbd without stopping both nodes simultaneously
(i.e. without the outage of the whole H-A cluster)?
