PowerProtect Data Manager 19.12 Microsoft SQL Server User Guide

Recommission the Microsoft application agent after Microsoft SQL Server hostname is changed or reused

Use the procedure in this topic to register and recommission the Microsoft application agent with PowerProtect Data Manager in the following cases:

• You changed the IP address (static IP), FQDN, or short name of the Microsoft SQL Server host that is registered with PowerProtect Data Manager.
• You unregistered the Microsoft SQL Server host from PowerProtect Data Manager and then registered a new host by reusing the same IP address and hostname of the former host.

Complete the following steps to register and recommission the Microsoft application agent.

1. Disable the protection policy before you change or reuse the IP address (static IP), FQDN, or short name of the Microsoft SQL Server host.

2. Decommission the host by deleting the asset source according to Delete an asset source. This procedure unregisters the host from PowerProtect Data Manager and removes the host assets after all the asset copies have expired.

   At this point, the assets and asset source of the original host are still in the "Deleted" state, unless the asset copies have expired and garbage collection has run.

   NOTE If you unregister and reregister the Microsoft application agent instead of completing this decommission step, then duplicated asset names might appear in the PowerProtect Data Manager UI.
3. Change the IP address (static IP) of the Microsoft SQL Server host.
4. Run the application agent installer and select the change option to register the Microsoft SQL Server host with the same PowerProtect Data Manager server.
5. Enable the protection policy to continue with the scheduled backups.
