Mikrotik Change Software Id Link <Bonus Inside>

Important Note First

You cannot arbitrarily change the Software ID. It is a cryptographic hash derived from your device's hard drive serial number (or NAND ID for flash storage).
Changing the hard drive changes the Software ID. Changing the license level does not change the Software ID.

The only practical reason to "change" the Software ID is when you need to transfer a paid license (Level 4-6) to a different installation (e.g., moving from a PC to a Cloud Core Router, or from one hard drive to another).


3. Installation & Setup

# Install dependencies
npm init -y
npm install express routeros-client cors dotenv

Error: "Failed to get license: Timeout"

Cause: The MikroTik license server is unreachable, or your router has no DNS. Fix: Set a proper DNS (8.8.8.8) and ensure the router can reach https://licence.mikrotik.com.

Scenario C: Migration

You are moving from an old Dell server to a new Supermicro server. You need to transfer your paid license.

In all these cases, you do not change the ID. You link the existing license to the new ID. mikrotik change software id link


RouterBoard / CCR (Physical MikroTik Hardware)

You rarely need to change the Software ID here. The license is embedded in the RouterBOOT. If you buy a used RouterBoard, the license stays with the board. If you need to transfer a license to a RouterBoard, you must use the "Sell" command on the old device first.

2. Changing Device Identity

You can change the identity of your device, which doesn't directly change the Software ID but changes how the device is identified on the network.

  • Change Identity: Go to System > Identity and change the identity of your device.
