PowerProtect Data Manager 19.13 SAP HANA User Guide

Migrate the SAP HANA agent to a different host

You can migrate to a different SAP HANA agent host and connect it with PowerProtect Data Manager by reusing the IP address and hostname of the former host.

Prerequisites

  1. 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.

    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 re-register the SAP HANA agent instead of completing this decommission step, then duplicated asset names might appear in the PowerProtect Data Manager UI.
  2. Ensure that a copy of the user and auto configuration files from the source host exists in the directory path on the destination host.
  3. Ensure that the operating system of the former application agent host is powered off.

About this task

This procedure is applicable for the following use cases:

  • Operating system upgrade of the application agent host
  • Service pack update

The operating system version of the new application agent host can be the same as or different from the operating system version of the former host. Perform the following steps to migrate the SAP HANA agent to a new host by reusing the same IP address and hostname as the former host.

Steps

  1. Register the new SAP HANA host with PowerProtect Data Manager and add the target asset to a protection policy.
    NOTE: When you specify the same IP address and hostname as the former host, PowerProtect Data Manager registers with the new host using the same agent ID.
  2. After the application agent host discovery, add the discovered assets to either an existing protection policy or a new protection policy.
  3. Restore the data from the former host to the new host. Performing alternate host recovery provides details about the process to restore the data from the former host to the new host.
  4. Validate the SAP HANA operations on the new host.
