Centos – Restore Zimbra Mail Server from Server that crashed

centosemailzimbra

I had a Zimbra installation which crashed due to Hard drive failure. The Zimbra was version 5. My backup was not good and so I did a fresh install and now I have managed to get the /opt/zimbra folder from the crashed hard drive. Is there anyone who can assist me in restoring or combining the current install with my backup? THe current install I have is version 8 of Zimbra. I want to combine the two so that users have access to their old mails. Old installation was a 32Bit CentOS 5 current is 64Bit CentOS 6.
P.s. Its the Open Source Version. ZCS

I would set up a separate machine with the old OS and ZCS, export the mailboxes and load the contents into the new setup. You can also use ldapsync for that, or even pull each mailbox with a IMAP/POP client out locally, and then push the contents into the new mailbox. You'll lose the calendar this way though.

Combining the two servers on the file level will probably cause more problems than it's worth, especially given the huge gap in versions in use.

Centos – Unable to install a fresh version of MySQL on CentOS

I think this is the problem:

You replaced the mysql57-community repo for EL7 with the one for EL6, but yum still has cached metadata for the EL7 repo. Try clearing the metadata:

yum clean metadata
