Quick question. If upgrading from K2 v5.3 to v5.4 on the same server, do I need to request a new license file, or can i just upgrade using the existing license for v5.3?
I am not entirely sure what causes a system key to change. As you can imagine, that is very super-secret hush-hush information. But, if you are on the same machine, and you have not made any significant changes, you should be able to just upgrade from 5.3 to 5.4 without issue.
