Reinstall activation

Hello,

 I'm planning on doing a fresh install of  Rockstor on the same system with the 3.9

I copied my UUID with the command above. Will this change with a new install ? Or will I need a new UUID for the same system ? The reason for the reinstall is because system is very sluggish and running slow.

please advise…

thanks

O.K.
Just finished re-installing Rockstor I tried using my UUID and that did not work on stable release updates. So I had to activate testing updates to get to 3.9 .

Where do I send my old UUID so I can get a replacement ???
