A critical element of our system relies on drbd. The OES2 SP3 to OES 11 upgrade is done hand-in-hand with the SLES 10 to SLES 11 upgrade.

SLES 10 has drbd 0.7, SLES 11 has drbd 8.3 . I gather that to upgrade drbd 0.7 to 8 requires the drbd metadata to be converted to a new format. I don't want the upgrade to zap my drbd.

Can I rely on the upgrade doing the right thing or am I better off doing the drbd upgrade separately first? Assuming I can install drbd 8 on SLES 10, of course.

Bear with me, I am a part time sysadmin.
