Yes, that should work, since all current 8.x drbd versions use the same 
network protocol and disk format (don't know about 8.3 though).

The heartbeat upgrade might be more difficult. Don't know about that.

If in doubt: try the upgrade on a test cluster. When doing HA, this is always 
a good advice anyway.
