Issue

When upgrading to a new version of the Messaging Operating System (MOS), what is the backup procedure?

Solution

NOTE: Before reading this article, Mirapoint highly recommends reading the latest version of the Mirapoint Backup and Restore Guide.

Do the following:

If you must revert to the previous MOS version for any reason, perform a disaster recovery and restore from Backup-1.

If the appliance needs disaster recovery after the upgrade, perform a disaster recovery and restore from Backup-2.

NOTE: Pre-3.2 Release appliances with address book, dictionary, WebMail, and WebCal cannot be correctly restored to post-3.2 appliances.
