I did a fresh install of 7.2.2 on a flash drive that is registered to an original Pro key. After I got the server booted I exported the boot drive and copied the key file into the config folder. After rebooting the server I'm now getting a License Key Mismatch error. I followed the prompts to recover my key via my unraid.net account but recovery fails. The server appears to be operating normally besides the initial error prompt I get about the key mismatch. I see the license structure and key management changed in 2024. Do I need to register my old keys or just ignore this error?

Background - I have two original Pro licenses purchased in 2013. One is running in my primary server with no issues. The second key was activated in 2018 but has been sitting dormant for about 6 years in a second server. I resurrected that server today because I'm beginning a major hardware refresh and wanted to run some tests on the new server before I transfer all my data over.

The GUI can sometimes show not updated info; check Tools - Registration. If all looks good there, it's fine; a reboot should also resolve the issues.
