How can you change the name on a device?

Thanks Niel. — Not sure if all concerns or solved yet since I now have two identical MacBook Pros on the same network. One has water damage so I replaced it and migrated its info onto the replacement computer, hence its same name and network. Biggest concern now is confusion with Adobe Creative Cloud's software permissions which still honors both the damaged MacBook Pro and the replacement MacBook Pro. I want the damaged computer to simply go away so that my primary computer, an iMac, can again function with all Adobe Creative Suite software. (2 machines are allowed but they turned off my IMac instead of the damaged MacBook Pro). Sorry about the deep dive explanation but hopefully I and Adobe will now see a different name (thank you) that will differentiate the two MacBook Pros.
