How to move from purchased Desktop Central integration to ServiceDesk supported Desktop Central

How to move from purchased Desktop Central integration to ServiceDesk supported Desktop Central

Hi,

I think I understand that the native Service Desk plus relies on an install of Desktop Central for agent services?

We have been using integration with a paid for Desktop Central for a time and have now moved away from Desktop Central, with only an option to run it as a "free version", which is limited to 25 devices.

What is the correct way of updating our integration for Service Desk Plus agents which are currently referencing the old Desktop Central?

Thanks,
Roy
