Make sure these requirements are in place before you begin restoring ePO - On-prem from a Disaster Recovery Snapshot.
ePO - On-prem SQL database containing a valid Disaster Recovery Snapshot.
User name and password for a global administrator account that uses ePO - On-prem authentication.
The Disaster Recovery passphrase for the snapshot in the database.
Install ePO - On-prem 5.10.2428.67 or later in Primary Node after enabling the Restore DB option.
Failover to the secondary node and complete the installation without enabling the Restore DB option. During this process expect unavailability of Tomcat service.
If you apply ePO - On-prem 5.10.0 Update 13 after taking snapshot on the previous ePO - On-prem 5.10.0 server, you must perform disaster recovery with ePO - On-prem 5.10.2428.67 or later, then perform the repair function with ePO - On-prem 5.10.0 Update 13.
When snapshot is taken on ePO - On-prem 5.10.0 Update 13, during Disaster Recovery restore, ePO package 5.10.0.2428.67 or later automatically performs the repair for Update 13, that means manual repair is not needed post Disaster Recovery restore.
