We have been running the following version for several years and today suddenly the server ran into a issue and we are being told it cannot be booted up normally and we have to salvage any data as backup from recovery mode and rebuild the server OS.
Version: zcs-NETWORK-8.8.8_GA_2009.UBUNTU14_64.20180322150747
OS: Ubuntu 14
currently we have NG Backup located at /opt/zimbra/ng_backup
I see the steps below, but does this restore require same version of zimbra and compatible ubuntu as the original or i can go with latest version of zimbra and OS and continue to restore from the NG backup done by older version of zimbra? the "/path/to/thhe/old/store" is /opt/zimbra/store?
The Recovery Process
Install Zimbra on a new server and configure the Server and Global settings.
Install Zimbra NG Modules on the new server.
Mount the Zimbra NG Modules Store folder of the old server on the new one. If this is not available, you use the last External Backup available or the latest remote backup.
Begin an External Restore on the new server using the following CLI command:
zxsuite backup doExternalRestore /path/to/the/old/store
The External Restore operation will immediatly create the domains, accounts and distribution lists, so as soon as the first part of the Restore is completed (check your Zimbra NG Modules Notifications) the system will be ready to be used by your users. Emails and other mailbox items will be restored afterwards.
