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.

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"?

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

It sounds like you're dealing with a license issue where your MikroTik Software ID

(SoftID) changed—perhaps due to a hard drive swap, formatting, or a VM migration—and you need to link your existing license to that new ID. How to Link or Update Your Software ID

If you have a paid license and your SoftID has changed, follow these steps to link the new ID to your account: For x86 (PC) Licenses: Log in to your MikroTik Account Navigate to the "Support Contact Form" support@mikrotik.com Provide your old Software ID new Software ID

. Note that MikroTik usually allows one license replacement for a fee or under specific conditions (like a failed HDD).

If it’s a simple typing error on a new purchase, you are often allowed to fix up to 2 characters for free. For Cloud Hosted Router (CHR):

CHRs do not use traditional "Software IDs" in the same way; they use a To link a license, go to System > License in Winbox. Renew License

, enter your MikroTik account credentials, and select your prepaid level. The license will then be automatically linked to your account portal, allowing you to move it between instances later. Upgrading from Old to New Format:

If you are on an older RouterOS version (pre-v3.25) and see a new SoftID format (XXXX-XXXX), use the "Update License Key"

button in Winbox while connected to the internet. This will sync the old key with the new ID format.

Drafting a Paper: Managing Software IDs in Network Virtualization

Since you asked to "draft a paper," here is a concise structured outline/abstract for a technical briefing on the subject:

To change the Software ID link on a MikroTik device, you essentially need to understand what the Software ID is and how MikroTik uses it. The Software ID is a unique identifier for the RouterOS software that is running on a MikroTik device. It is used by MikroTik for various purposes, including licensing, support, and version identification.

Changing the Software ID on a MikroTik device is not a straightforward process and typically involves changing the device's identity, which can have implications for device management, licensing, and support. Here is a detailed report on the context and steps involved:

Conclusion: There is No Magic Link, Only a Process

To directly address the search term "MikroTik change software ID link":

• You cannot change the Software ID arbitrarily; it is a secure hash of your hardware.
• The "link" is not a button in RouterOS; it is the process of re-hosting your license on the MikroTik website.
• The only way to "change" it is to physically alter your hardware (for x86) or run generate-new-id (for CHR), then manually re-link your license via your MikroTik account page.

Remember, for official MikroTik RouterBOARD hardware (RB, CCR, CRS series), you will never need to perform this process. For CHR and x86 users, mastering the re-host workflow is essential for disaster recovery.

Next Steps: Bookmark the official MikroTik Wiki page on Licensing and always keep a backup of your license keys on a separate cloud drive. A changed Software ID without a valid license link is just a very expensive paperweight.

Part 4: Step-by-Step Guide – How to Change/Re-link the Software ID

Let’s assume your hardware has changed (you replaced a drive) and RouterOS now shows a new Software ID. Your previously activated license is now showing as "Unregistered" or "Trial." Here is how to fix it by changing the linked ID.

Script: change software-id on MikroTik RouterOS via terminal

Run this in RouterOS terminal (adjust interface name and target MAC/ID as needed):

/system identity set name="New-Router-Name" /interface ethernet set [find name="ether1"] mac-address=AA:BB:CC:DD:EE:FF /system routerboard settings set software-id="NEW-SOFTWARE-ID-HERE" /system reboot

Notes:

• Replace "New-Router-Name", interface name, MAC and software ID with desired values.
• Changing RouterBOARD software-id may not be supported on all models or RouterOS versions and can risk warranty or license issues; ensure you have backups and a valid license.

In MikroTik’s RouterOS, the Software ID is a unique identifier generated based on your storage drive’s signature. It is used to lock a license to a specific piece of hardware. Because it is tied to physical (or virtual) disk characteristics, you cannot manually edit or "change" it through the terminal or WinBox settings. However, you can

a new Software ID to an existing license if you are replacing hardware or moving a virtual machine (CHR). 1. How to Find Your Software ID

Before you can transfer or link a license, you need the ID from the new device: /system license print 2. Linking a License to a New Software ID (Replacement)

If your hardware fails or you migrate a VM, MikroTik allows a one-time "License Replacement." This links your old license to the new Software ID. Log in to your account at mikrotik.com Navigate to "Make a key from a replacement key" (or use the Support Contact Form if the option is missing). Old Software ID New Software ID

MikroTik's system will generate a new key for you to paste into the new device. 3. Using CHR (Cloud Hosted Router)

For virtual machines, MikroTik uses a different system called Cloud Hosted Router (CHR) You link your CHR instance to your account by going to /system license in the terminal and entering your account credentials. Transferring:

If you move the VM and the Software ID changes, you can simply log in on the new instance, and the MikroTik Account Management page allows you to move the "active" license to the new ID. Common Misconceptions Router Identity vs. Software ID:

Users often confuse "Software ID" with "Identity." If you just want to change the router's name (e.g., "Core-Router"), go to HDD Cloning:

If you clone a disk, the Software ID usually changes because it detects a different physical drive or partition UUID. You will almost always need to perform a license replacement through the MikroTik Support Team

Are you trying to move a license from a broken router, or are you setting up a new Virtual Machine (CHR)?

Knowing this will help me give you the exact steps for your specific scenario. RouterOS license keys - MikroTik

Part 6: Advanced – How to Change the ID via Script (API)

For automation engineers, you can trigger a Software ID change (on CHR only) via the API. This is the closest thing to a direct "link" command.

API command to generate new CHR ID:

/system license generate-new-id

API command to renew license post-change:

/system license renew

This is powerful for scripting recovery in dynamic cloud environments where VMs are cloned or migrated.

Can You Fake/Change Software ID Without Hardware Change?

No. Here is why:

| What you try | Result | |-------------|--------| | Change date/time | No effect | | Reinstall RouterOS same disk | Same Software ID | | Clone hard drive | Same Software ID (duplicate) | | Use software patches ("cracks") | Breaks license, unstable router |

The only legitimate ways to get a different Software ID:

1. Replace the storage (HDD, SSD, USB drive, or NAND chip).
2. For x86 PC: Use a different hard drive.
3. For RouterBoard: Not possible without soldering (not recommended).
