How to move Sharepoint 2010 to a new Virtual Machine?

Hi All

I have Sharepoint 2010 running on a VM, which is connected to a VM running SQL 2008.

I want to build a new VM for Sharepoint 2010, as the current one is pretty poor. How do I go about setting up a new VM and moving Sharepoint 2010 to that new server and linking it to the SQL database/server with minimal chance of problems? 

Any guides etc online?
