Upgrading for drbd/heartbeat
I have ZCS 6 installed on CentOS 5 and would like to upgrade to version 7. I have a primary and secondary (standby) node. Data is replicated to the secondary node (/opt/zimbra) using drbd and heartbeat is used for server monitoring/failover.
After I extract the the version 7 tarball and run ./install.sh on the primary server, the changes that the upgrade script makes to /opt/zimbra should be replicated to the secondary node. Since I only replicate /opt/zimbra, are there files outside of this that I should be copying over from the primary to secondary node manually that are changed during the upgrade process?
Also, will Outlook connectors from version 6 still work after zimbra has been upgraded to version 7?
