upgrading DRBD 8.2.6 to 8.3

in the middle of formatting the /dev/drbd0, i found out from:
http://www.howtoforge.com/drbd-8.3-third-node-replication-with-debian-etch
...that i actually need to have version 8.3 for 3 nodes (2 + 1 config,
2 active/primary, 1 standby/secondary)
anyone can share their experience upgrading from 8.2.6 (currently
configured 1 primary, 1 secondary) to 8.3 (2 primary,1 secondary) ?
the tricky part is, i also did not configure lvm2-cluster for both PVs
(2 LUNs, one for each primary nodes, but secondary supposed to see
both)
current drbd.conf
------------------------
global { usage-count no; }
resource repdata {
protocol C;
startup { wfc-timeout 0; degr-wfc-timeout 120; }
disk { on-io-error detach; }
net { cram-hmac-alg "sha1"; shared-secret "pA$sW0rD"; }
syncer { rate 10M; }
on mailserver01.servers.com.my {
device /dev/drbd0;
disk /dev/Zimbra-DRC/mailserver01;
address 192.168.1.100:7788;
meta-disk internal;
}
on mailserver02.servers.com.my {
device /dev/drbd0;
disk /dev/Zimbra-DRC/mailserver02;
address 192.168.1.200:7788;
meta-disk internal;
}
}
any thoughts/opinion?
