[DRBD-user] Moving a live DRBD setup to a new version?

Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I have DRBD 8.0.16-5.el5.centos installed and primary and secondary running
fine on a two node system.

We needed to add more storage so we took the secondary node down rebuilt the
array, reinstalled the OS and are reinstalling services. At the point of
reinstalling DRBD I am seeing that CentOS 5.5 wants me to install the drbd82
package rather than drbd package.

Can I install the drbd82 and kmod-drbd82 package and configure it to become
a secondary to the old primary node running the old DRBD version to get the
data to the larger array, make the new set up primary and then rebuild old
primary to match new or will I have an issue with the two versions of DRBD
correctly syncing data?
