[DRBD-user] Compatibility between two different versions of DRBD 0.7

We have a cluster of two nodes with Debian Sarge 3.1 , DRBD 0.7.10-4
(debian packages), and Linux Kernel 2.6.8-2-686.
The primary node died due to a hard drive failure, and the second node
becomes primary, no problem.
I want to reinstall the first node with newer packages (Debian Etch 4.0
, DRBD 0.7.21-4 (debian packages), linux kernel 2.6.18-4-686) and I
wonder if 2 differents versions of DRBD 0.7 are compatible or not ?
I saw in the archives that DRBD 0.8 and DRBD 0.7 are not compatibles,
but I found nothing in the user's guide about compatibility between 2
versions of DRBD 0.7.
Besides, we recently had these errors with kernel 2.6.8-2 and need to
"kernel: PREEMPT SMP
kernel: <6>note: nfsd exited with preempt_count 1"
I think these errors are due to a kernel problem with NFS server, and I
wish to take advantage of the reinstallation of the died node in order
to have a newer version of the Linux Kernel and DRBD.
Can I install Etch in my server or should I stay with Sarge ?
Thanks for your replies,
