Upgrading: Oops, wrong version! Help!

[frankman]

I'm on ZCS OS 6.0.10 on CentOS 5-64bit, single server setup.

I was doing an upgrade from ZCS OS 6.0.10 -> 7.1.2, but I downloaded the Redhat 6 version of 7.1.2, instead of Redhat 5 version.

So the upgrade quit due to error:

# ./install.sh --platform-override

As you can see, it removed the 6.0.10 installation. I'm downloading ZCS 7.1.2 for Redhat 5.

I'm worried now if running the 7.1.2 install will perform the upgrade properly.

Should I do just that and run the 7.1.2 installer?
Or should I re-run the 6.0.10 installer (still have a copy of it), then run the 7.1.2 upgrade?

Help!

By the way, I did a full backup before running the installer. Even if I rsync the backup back to /opt/zimbra, I think the rpm database will show that 6.0.10 is gone and no zimbra is installed, yet it is.

So will 7.1.2 will think it's a fresh installation and not do an upgrade, just a fresh install?

[frankman]

Solved it.

When in the old 6.0.10 package directory and manually `rpm -Uvh` each zimbra-* package that were installed (no memcache, proxy, etc.). This fixed the rpm db problem.

Then did an rsync from the backup to /opt/zimbra. This fixed the config files because they were modified from the 7.1.2 install.sh script.

Then ran the 7.1.2 install.sh again and it all worked.
