Greetings,

Need to move a DPM server to new hardware including a Tape Library autoloader.
I was thinking :

  1. Build new W2019 DPM2019 SQL 2017, fully patch
  2. Connect all existing DPM agents to new DPM server, recreate Protection Groups
  3. Reconnect Tape Library and import reinventory / tapes.

If that all works and I need to restore from the old DPM server (disk restore) can I until the new server has built up the new Disk backups..

As ever tips appreciated

    "Reconnect any other storage"

    One more question, the old DPM server has local (RAID) storage for the short term disk backups, the physical RAID can't be moved to the new server
    Can I migrate the stort term to disk backups also to the new DPM server ?

    Hi @Pompy George ,

    The best way to do this is to simply:

    • Install a new Windows Server on the side
    • Install the exact same SQL Server with same updates (must be the same version)
    • Cancel all pending scheduled backup jobs and wait for running jobs to complete
    • Backup the DPM database
    • Copy the DPM database backup to the new server
    • Shutdown the old DPM server
    • Restore the DPM database on the new server
    • Install DPM 2019 + eventual Update Rollups (must be the same version), choose existing database
    • Reconnect the tape library and import/re-inventory the tapes
    • Reconnect any other storage
    • Run the following command: DPMSync -Sync
    • Open the DPM console and check agent communications and make sure DPM storage pool disks look good- then run consistency checks on all data sources.

    There's no need to remove any protection group really, but if you feel like you want to do that, feel free to.

    Hey Leon,

    So it looks like :

    Install a new Windows Server - new IP address but same server host name as old DPM server

    Fully patch the server

    Install SQL Server with updates (must be the same version as the old DPM server)

    On the old DPM server cancel all pending scheduled backup jobs and wait for running jobs to complete

    On the old DPM server Backup the DPM database - Using SQL Mgmt Tools

    Copy the backup of the DPM database backup to the new server

    Shutdown the old DPM server

    Restore the DPM database on the new server using SQL Mgmt Tools

    Install DPM 2019 + eventual Update Rollups (must be the same version), choose existing SQL database

    Reconnect the tape library and import/re-inventory the tapes

    Reconnect any other storage

    Run the following command: DPMSync -Sync

    Open the DPM console and check agent communications and make sure DPM storage pool disks look good- then run consistency checks on all data sources.
