I needed to replace my USB stick, so i followed the instructions, and put the backup on the new USB Stick, now i get this message from UNRAID, and i dont see the option replacing the key. 

I found the Solution, there was for some reason more then one key on the USB Stick. I guess this is a bug, no idea how this can happen. as the Trail key is normal to have, i thought it get deleted after i purchased a license. ok a new thing to know

Just coming across this as I was replacing my defective USB. What solution did you find? How did you resolve it?

Delete all keys from the flash drive except the last valid one, they are in the /config folder.

Found it. I had a Basic and a Pro. Removed just the Basic. After reboot, it then allowed me to transfer the key. Thanks!

Hi everyone,

is this still a thing? Iam a unraid newbie and my first choice for the USB Stick was not smart. Now I will get a new stick I would like to use in the next days and while I strayed a bit in the config backup I noticed that it includes a starter.key and the older trial.key. Could this cause problems. Thank you in advance?

Just delete the trial key and then you don't have to worry about it.

Worth considering the latest beta and skip the USB altogether.

Version 7.3.0-beta.2 2026-04-01 | Unraid Docs

This beta adds dedicated boot pool support and fixes user-facing regressions reported against 7.3.0-beta.1, especially around Docker behavior, XFS sector-size compatibility, onboarding polish, and dev

Hi guys,

thank you for the swift reply.

Because my first installation included a lot of try and error I decided to purge the stick and make a clean new start,

because I used the old stick it was simply able to fetch the license, so the issue "solved" itself.

@Veah Thats interesting also for binding the license to tpm. My hardware (ugreen dxp2800) is tpm capable so maybe I skip the license migration to the stick and wait for this to be become stable release.

Again, thank you for the input.

One thing worth remembering is that internal boot has several drawbacks and only a few advantages.

Read up on it first, then decide for yourself.

Marketing materials don’t tell the whole story.

A good place to start is the USB Flash guide in the Boot Devices category of this forum.
