I thought the website was meant to do that for you?
Is the new property a new build?
Do you know if there is an occupant in there now with a currently working VM connection. If so then it ought to be straight forward - if not.... well I dont believe VM test the connection before you move - they just "know" whether there has been a previously active account in that property and not whether it is currently a "quick start" option with an active connection.
Most go through ok quickly.. but there is a small % of these that hit issues for various reasons (e.g previous occupier removed wall boxes, or decorated over them, exterior cables are damaged, etc)
