How to Fix SSD Migration Error on Windows 11: Complete Troubleshooting Steps

Upgrading to an SSD can significantly improve your computer’s speed and performance. However, encountering migration errors during the process can be frustrating. These errors usually happen when copying or moving your system files to the new SSD.

Fixing SSD migration errors on Windows 11 requires careful troubleshooting to ensure your data is safely transferred. Fortunately, many common issues can be resolved with simple steps.

This guide will walk you through easy and detailed troubleshooting steps. You don’t need to be a tech expert to follow along.

By the end, you’ll know how to handle the migration error and get your SSD running smoothly.

Quick Note: Prerequisites and Initial Checks

Before you start troubleshooting, make sure of the following:

  • Backup Important Data: Always back up your files before migrating to avoid any data loss.
  • Check SSD Compatibility: Ensure your SSD supports your system and is properly connected.
  • Confirm Sufficient Space: The SSD should have enough free space to hold the data you want to migrate.
  • Update Windows and Drivers: Running the latest updates can fix compatibility issues.
  • Use the Correct Migration Software: Use tools recommended by your SSD manufacturer or trusted third-party software.

Step 1: Restart Your Computer and SSD

Sometimes, a simple restart can resolve minor glitches. Power off your PC, disconnect the SSD, then reconnect it properly. After that, turn your computer back on.

This refreshes hardware connections and clears temporary errors that might cause migration problems.

Step 2: Run Disk Check on the SSD

Errors on the SSD can block migration. Running a disk check helps find and fix these issues.

Follow these steps to run a disk check:

  1. Open File Explorer and find your SSD drive.
  2. Right-click on the SSD and select Properties.
  3. Go to the Tools tab and click on Check under Error checking.
  4. If errors are found, follow on-screen instructions to repair them.

This ensures your SSD is healthy before starting migration.

Step 3: Disable Security Software Temporarily

Sometimes antivirus or firewall programs interfere with migration. Temporarily disabling them can help complete the process.

To disable Windows Defender temporarily:

  1. Open Settings from the Start menu.
  2. Go to Privacy & Security > Windows Security.
  3. Click on Virus & Threat Protection.
  4. Under Virus & Threat Protection Settings, select Manage Settings.
  5. Turn off Real-time protection.

Remember to turn your security software back on after migration is complete.

Step 4: Run Migration Software as Administrator

Running the migration tool with administrator privileges ensures it has the necessary permissions to modify system files and drives.

To do this:

  1. Right-click on the migration software shortcut or executable file.
  2. Select Run as administrator.
  3. Proceed with the migration process.

This helps avoid permission-related errors during migration.

Step 5: Check for Partition Style Compatibility (MBR vs GPT)

Your system drive and the SSD must use compatible partition styles. Windows 11 usually requires GPT (GUID Partition Table).

To check the partition style of your drives:

  1. Press Windows + X and select Disk Management.
  2. Right-click your current system drive and select Properties.
  3. Go to the Volumes tab and look for Partition style.
  4. Repeat for the SSD.

If the SSD uses MBR while your system drive uses GPT, you may need to convert the SSD to GPT.

To convert MBR to GPT without data loss:

mbr2gpt /convert /disk:<disknumber> /allowfullos

Replace <disknumber> with your SSD’s disk number from Disk Management.

This command requires Command Prompt to be run as administrator.

Step 6: Use a Different Migration Tool

If the error persists, try using alternative migration software. Some popular tools include:

  • Macrium Reflect (Free and Paid versions)
  • EaseUS Todo Backup
  • AOMEI Backupper

These tools often handle migration differently and may bypass the error you encountered.

Step 7: Update SSD Firmware

Outdated firmware can cause compatibility and migration issues.

To update firmware:

  1. Visit your SSD manufacturer’s official website.
  2. Download the latest firmware update tool.
  3. Follow the instructions provided to update your SSD firmware.

Firmware updates improve stability and performance.

Step 8: Reset Windows or Perform a Clean Installation (Advanced)

If migration continues to fail, resetting Windows or doing a clean install on the SSD may be necessary.

This is the last resort as it involves reinstalling the operating system and applications.

Make sure to back up all your data before proceeding.

Reset Windows 11:

  1. Go to Settings > System > Recovery.
  2. Under Reset this PC, click Reset PC.
  3. Choose whether to keep your files or remove everything.
  4. Follow the on-screen instructions.

After resetting, you can install Windows directly on the SSD.

Frequently Asked Questions (FAQs)

Why am I getting an SSD migration error?

Errors can occur due to insufficient space, incompatible partition styles, corrupted files, or interference from security software.

Can I clone my SSD instead of migrating?

Yes, cloning copies your entire drive sector-by-sector and is often used as an alternative to migration.

Is it safe to disable antivirus during migration?

Temporarily disabling antivirus is generally safe but ensure you enable it again right after the process to keep your system protected.

How do I check if my SSD supports Windows 11?

Check the manufacturer’s specifications for compatibility, including support for Secure Boot and TPM 2.0, which are Windows 11 requirements.

What if the migration tool freezes or crashes?

Try running it as administrator, use a different tool, or check for system resource issues like low RAM or disk errors.

When Nothing Works

If you have tried all the above steps and still face migration errors, consider these final options:

  • Contact SSD Manufacturer Support: They can provide specific tools or advice for your model.
  • Visit Microsoft Support: Official help for Windows 11 migration issues is available through Microsoft’s website.
  • Consult a Professional Technician: If you’re uncomfortable with advanced steps, a technician can assist safely.

Conclusion

Fixing SSD migration errors on Windows 11 is often straightforward if you follow the right steps. Begin with simple actions like restarting and checking for disk errors before moving on to partition style checks and software alternatives.

Understanding why each step matters helps you avoid common pitfalls and ensures a smooth transition to your new SSD. Remember to keep backups and update your system regularly to minimize issues.

With patience and the right approach, you can successfully migrate your data and enjoy faster performance with your SSD.
