Moving 3CX Phone System to a New Machine

Moving 3CX Phone System to a New Machine

Step 1: Backup the Existing Installation

Step 2: Deactivate your License

Step 3: Preparing and Installing

If you need to move 3CX Phone System to a new machine the procedure is as follows:

Step 1: Backup the Existing Installation

  1. Run the “3CX Backup and Restore Tool”
  2. Select “Backup 3CX Phone System”.
  3. Choose which components you would like to backup. For a full backup select all checkboxes.
  4. Select the path and filename to save the backup to (choose a location that is accessible by the new machine).
  5. Click “Next” to backup.

Step 2: Deactivate your License

  1. In the 3CX Management Console, select “Settings” > “Activate License” .
  2. Click on “Free Version” to deactivate your license on this machine.
  3. You can now switch this machine off.

Step 3: Preparing and Installing

  1. Prepare the new host for 3CX as outlined in the “Preparing the Windows host machine for installation” section of the "Installing 3CX Phone System" guide.
  2. Install 3CX Phone System on the new machine in exactly the same way as described in the Download and Install 3CX Phone System section.
  3. Configure your new installation as described in the 3CX Phone System Configuration Wizard section.
  4. When the wizard gives you the option to restore settings from a backup, (Backup created from your previous installation of 3CX), locate your backup and restore.

Once this has completed, you can log on to the new 3CX Management Console and re-activate your license as described in the Activating 3CX Phone System section.

Note: Configure your firewall to point all the ports, opened for the old system,  to now point to the new systems’ internal IP Address.

Your new installation of 3CX Phone System, complete with all your settings, is now ready for use.

    If I move the PBX to a new machine with a different internal IP address and name, do I have to re-provision the clients?

      @Al, If the system is v14 and you installed with No FQDN or External FQDN and Internal IP then internal phones and 3CX Clients will need reprovisioning. If though you installed with Single FQDN using split DNS you simply need to change the IP address of the A record within your internal DNS server, for the host part of the FQDN, to point to the new machines IP. If v15 and installed with external FQDN and internal IP the same applies. The same also applies to split DNS in v15. If v12.5 and used internal IP instead of FQDN then again reprovisioning is going to be required.

      I want to back up my v14 and restore to v15 on a new server with new IP address. Where is internal FQDN set? If I look in Settings/Network on the management console there is a FQDN set, but if I generate a welcome email the config file has a local address of 10.20.1.7.

      I would like to change this to a DNS name before the backup/restore if possible.
