Migrating SOLIDWORKS SolidNetWork License Manager (SNL) to a new server may sound intimidating at first, especially when the move affects all your SOLIDWORKS users. This guide provides detailed steps to move the SNL to a new server as well as redirect the clients to connect to the new server with minimal downtime.

  1. Configure the NEW server port rules 
  2. Install SolidNetWork License Manager on the NEW server 
  3. Add the NEW server to each client SNL server list 
  4. Add the NEW server to the PDM Administration tool (if using PDM) 
  5. Deactivate/Transfer the licenses from the OLD SNL server 
  6. Activate the license on the NEW SNL server

Step #1: Configure the New Server Ports

If a firewall is in place on the new server, verify the required ports the SNL uses for communication are added to the inbound and outbound exception rules. The default installation requires TCP ports 25734 and 25735 to communicate between the SNL server and clients.

PDM SNL Changed

Note Before Continuing

Once the client computers and SOLIDWORKS PDM administration tool have ALL been updated so they are displaying the old and new server on the Server List tab, you can proceed with the license transfer. This process should only take 5-10 minutes to complete. During the transfer, users currently consuming a network license will continue to work without interruption for approximately 1-hour. After 1-hour, at which time users will receive a warning that the license manager is down and that they have 20-minutes to save their work. 

 

This should provide adequate time to perform the transfer without any interruption, though we recommend performing the process at a time of user inactivity and to have MLC CAD Systems technical support number on hand just in case any unexpected behavior is experienced. Submit a technical support case 

 

After Step #5, any user who attempts to launch SOLIDWORKS will receive a message that a license is not available until Step #6 is completed. 

Step #5: Deactivate/Transfer the License from the OLD SERVER

On the OLD server that will no longer be used for SOLIDWORKS licensing, launch the SolidNetWork License Manager Server 20XX application. On the Server Administration tab, click the Modify… button. In the SOLIDWORKS Product Activation dialog, select the option Move your product license(s) to a new/upgraded computer and then click Next. Follow the prompts to complete the transfer. Now the licenses can be activated on the new server. 

Deactivate Old SNL

Step #6: Activate the Licenses on the NEW SERVER

On the NEW server, launch the SolidNetWork License Manager 20XX application. On the Server Administration tab, click the Modify… button. In the SOLIDWORKS Product Activation dialog, select the option Activate/Reactivate your product license(s). Follow the prompts to complete the activation. Detailed instructions can be found on page 4 of the SolidNetwork License Manager Installation Guide

Step #7: Remove the OLD SERVER from each Client SNL Server List

Click the Remove… button  and then Yes when prompted to remove the selected item(s). The old server will no longer be listed. Repeat the process for all client computers.
