Hi Stephanie. I am assuming you are in the UK?

You will not be able to move a Sage 200 CRM database to SageCRM.com due to a slightly different format of the database. You could possibly migrate the base data, company, person, opportunity etc via a tool such as InaPlex but it will not be able to link to Sage 200 from the cloud. You can however host Sage 200 CRM on a private cloud server and point it at your local installation of Sage 200. We do this for a few clients for both Sage 200 and Sage 50 integration. There are some potential issues around connection speed etc to consider first though.
