WAVE: How do I uninstall WAVE and revert to an older version?

  • Updated

Applies to Models:  Wisenet WAVE

Summary:

Although it is never recommended to downgrade a Hanwha WAVE System, there are certain cases where a user may need to downgrade their Hanwha WAVE System after an upgrade to the latest release. This article outlines how to accomplish a downgrade.

NOTE: WAVE automatically creates a backup of the previous version database 
before every upgrade.
NOTE: Our Software Development team only addresses software-level issues on 
the most recent release of WAVE. If you revert to an older version, you would
be forced to upgrade should any issues arise.

Step By Step Guide:

To uninstall WAVE and revert to an older version:

  1. Stop the Hanwha Media Server service.
    NOTE: This process may cause the Recording Licenses to drop out of the 
    database. Export your Recording Licenses under System Administration > 
    Licenses. Click the Export button in the top right of the License screen, 
    and save the license key list to your desktop.
  2. Navigate to:

    • In Windows
      C:\Windows\System32\config\systemprofile\AppData\Local\Hanwha\Hanwha Media Server

    • In Linux
      /opt/hanwha/mediaserver/var

  3. Locate the current ecs.sqlite and move this file to a folder on your desktop.

  4. Navigate to the backup directory, which is in the same directory as the ecs.sqlite.

    Example (in Windows):
    C:\Windows\System32\config\systemprofile\AppData\Local\Hanwha\HanwhaMediaServer\backup
    Linux - /opt/hanwha/mediaserver/var/backup

  5. Copy all the files out of the directories above to your desktop.

  6. Uninstall WAVE via the Windows Control Panel.

  7. Re-install the prior version you wish to roll back to.
    NOTE: You can obtain older versions from support. The version you restore 
    must match your backup file.
  8. Set up the new install as a New System in the Setup Wizard.
    This creates new ecs.sqlite.

  9. Stop the Hanwha Media Server Service.

  10. Find the backup file you wish to put back into the system.
    NOTE: ecs_36634_1689352709991_timer.db - ecs_36634 indicates this backup 
    file was from WAVE Build 36634. You could also look at the modified date 
    and select the most recent backup file.
  11. Rename the new file to ecs.old and rename the backup file to ecs.sqlite.

  12. Start the Hanwha Media Server Service.

  13. Log in to WAVE and verify your server is operational.
    NOTE: These steps must be repeated for every server in a multi-server system.
  14. If your server(s) are connected to WAVE Sync, re-establish this last, after all of your servers are functional.
