Do I need to buy Endpoint Central for scanning assets in SD?

Do I need to buy Endpoint Central for scanning assets in SD?

We have SD 12000 now, enterprise perpetual license with AMS expired. For some reasons IT asset scanning was disabled years ago, but we want to implement it again. I downloaded Endpoint Central, install it on the same server, but it says it will work for one month (less now). So, the question is - do we need to buy Endpoint Central for scanning assets, or it will work after the 30 days? Oh, and can I move it to another server? Thanks.
