Good guide. I took the following steps and it went quickly and smoothly. Less than an hour start to finish:

1. I purchased a Samsung 980 (not Pro, but should also work).

2. Disabled bitlocker on my old SSD. I also backed up the key for future ref.

3. Downloaded and installed the Samsung SSD Magician and migration tools.

4. Put the new SSD into an external enclosure ($18 on Amazon).

5. Ran the migration software and copied my windows 11 to the new SSD.

6. Shutdown the laptop and swapped the SSDs.

7. Rebooted into windows.

8. Ran the Samsung Magician software and updated the SSD firmware.

9. Done and perfect.
