I am looking into purchasing the pro license and wanted to know if it is limited to the one physical machine and unlimited drives (up to 26) or can I use the same key on other hardware?

The license is tied to the USB drive used to boot Unraid so it can only be used on one machine at a time.

If what you want to know is can you buy one license and run multiple machines from it, then no.

 

If what you want to know is can you change hardware and use the same license, then yes.

Thanks!
