Subject: Assistance with NX Witness Server Migration

Hi NX Witness Team,

Good day.

We are seeking your assistance as we are planning to migrate our NX Witness system from an old Windows server to a new Windows server.

Current Structure

Main Server

• Server 1 – to be replaced
• Server 2

Proposed Structure

Main Server

• Server 1 – old server to be decommissioned
• Server 2
• Server 3 – new replacement server

All our existing CCTV recordings are currently stored on a NAS. The new server has already been built and has been assigned a new IP address.

Could you please advise on the recommended migration process for replacing Server 1 with Server 3 while retaining access to all existing recordings stored on the NAS?

We would also appreciate your advice on whether we need to back up and restore the NX Witness configuration from Server 1, or if there is a recommended method for transferring the server configuration within the existing NX Witness system.

  Hi Norman,

  I would just like to confirm whether this is the correct guide for our situation, as we will still be using Network Optix Nx Witness and are not migrating to Network Optix Nx Go.

  The guide states:

  “This guide uses a migration from Network Optix Nx Witness to Network Optix Nx Go as an example.”

  Could you please confirm whether the same migration process applies when migrating Nx Witness to Nx Witness on a new Windows server?

  Hi johns ,

  My recommended workflow is:

  1. Merge in Server 3 and add NAS storage pool
  2. Stop all recording on Server 1 incl NAS, but leave online
  3. Move all cameras from Server 1 to Server 3
  4. When a suitable retention period has passed, delete / retire server 1
  5. Export / Backup licenses [for safety] and deactivate “Server not found” licenses, then reactivate them on Server 3 [Pro licenses only].

  Nx Client / Server will continue to access and recycle storage on Server 1 while it is online.

  Having multiple servers share the same NAS storage pool requires some specific handling;
