If the old serial is being retired or replaced, deactivate it first so the activation isn't stranded on the server. 1. On the license server, open **Start \> SOLIDWORKS Tools \> SolidNetWork License Manager Server 20XX** (right-click \> *Run as administrator*). 2. Go to the **License Administration** tab and click **Modify**. 3. Select **Move product licenses to the SOLIDWORKS server** and click **Next**. 4. Click **Select All**, then **Next**, and let the transfer complete. 5. Click **Finish** and close the SolidNetWork License Manager. ### Step 2: Enter the new serial number Where you enter the serial depends on the SNL Manager version on the server. #### SOLIDWORKS 2023 and later (inside SNL Manager) 1. Open **SolidNetWork License Manager Server 20XX** as administrator. 2. On the **Server Administration** tab, click **Modify** in the **License Information** section. 3. Select **Activate/Reactivate** and click **Next**. 4. Click **Next** again to keep the existing port and firewall settings. 5. Click **Add** and paste the new serial number(s) into the **Add Serial Number** window. 6. If you are retiring the old serial (deactivated in Step 1), highlight it and click **Remove**. 7. Continue through the wizard. It goes straight into activation, so pick up at Step 3, item 5. #### SOLIDWORKS 2022 and earlier (Control Panel) 1. Open **Control Panel \> Programs and Features**. 2. Select **SOLIDWORKS SolidNetWork License Manager** and click **Change**. 3. Click **Next** on the welcome screen. 4. Select **Modify** and click **Next**. 5. On the serial number page, enter the serial numbers **separated by commas** (old and new, unless you're retiring the old one). Click **Next**. 6. Click **Install** to complete the modification, then go to Step 3. ### Step 3: Activate the new license 1. Open **SolidNetWork License Manager Server 20XX** as administrator. If prompted that the product is not activated, click **Yes** and skip to step 4. 2. Otherwise, go to the **License Administration** tab and click **Modify**. 3. Select **Activate/Reactivate your product license(s)** and click **Next**. 4. On the **License Server Information** page, confirm the port (default **25734**). If a firewall is running on the server, check **A firewall is in use on this server** and enter the vendor daemon port (default **25735**). Click **Next**. 5. Click **Select All** to choose every product on the serial. 6. Enter a contact email address and choose **Automatically over the Internet** (recommended) or **Manually via e-mail**. Click **Next**. 7. Confirm each product shows as activated, then click **Finish**. ### Step 4: Verify the license server 1. In SolidNetWork License Manager, open the **Server Administration** tab and confirm the server status is running. If not, click **Start**. 2. Open the **License Usage** tab and confirm the expected products and seat counts appear. ### Step 5: Update the serial number on client installs Client installs also need the new serial number.
