Managed System Setup

Hi,

I have installed a new solution manager 7.1, upgraded to SP5 and am running the managed system setup to an ERP ECC 6 system on 7.02.

This will become the production solution manager and I need to move the managed systems from the DEV server to the PRD solution manager. The SLD will remain on the DEV solman. Is there a process to follow to remove the managed systems from DEV solman and add them to the PRD solman? Or should I install another diagnostic instance on the managed system for the PRD solman to manage? If so, do I require another host agent?

I've struggled to find any documentation on changing managed systems to a different solman.

Thanks

Grant
