Changing a MikroTik Software ID (SoftID) is not possible through standard settings because it is a unique identifier generated based on your hardware's storage media (NAND or HDD).
Because licenses are bound to this specific ID, changing it would immediately invalidate your current license. Common Scenarios for "Changing" the ID
While you cannot manually edit the ID, you may need to manage it in these specific situations:
Replacing Hardware (HDD/Flash): If you replace the drive on an x86 system, the SoftID will change. You can request a one-time "License Replacement" key from MikroTik support or through your account on mikrotik.com. mikrotik change software id link
Virtual Machines (CHR): In Cloud Hosted Router (CHR) environments, the System ID is tied to the VM's UUID. You can transfer a CHR license to a new instance by logging into your account and using the Transfer button.
Typing Mistakes (x86): If you made a mistake while manually entering a SoftID on the website to generate a key, MikroTik allows a free correction of up to 2 characters before the key is upgraded.
Generating a New ID (CHR): You can use the command /system/license/generate-new-id, but be warned: this wipes your current license and puts the device into free mode. Do You Actually Mean "Identity"? Changing a MikroTik Software ID (SoftID) is not
Users often confuse the Software ID (for licensing) with the System Identity (the router's name). If you just want to change how your router identifies itself on the network: RouterOS license keys - MikroTik
MikroTik uses the Software ID to bind software licenses to physical hardware. When you purchase a license, you provide this ID to MikroTik. Their system generates a license key (a specific text string) that only works on a machine producing that exact Software ID.
Think of it as a fingerprint. Every time RouterOS boots, it calculates this fingerprint. If the hardware changes, the fingerprint changes, and your paid license becomes invalid. How is it used
Changing the Software ID directly isn't typically supported through a simple configuration change. However, here are some scenarios and solutions:
When people say "Software ID link," they usually refer to one of these:
/system license. You likely need to re-run the re-host process.
