Let's pick a station number 2010 for example and that number is currently assigned to the remote switch. You currently have 2010 in your UDP table being routed to the remote system. If your UDP search parameter are to use the UDP table first, a call to 2010 will be sent to the other switch before looking to see if there is a local station.

To stop that from happening you will have to remove each station from UDP when you move it. On the other hand, if your UDP search parameters are to check for a local station first then it will see the new phone and send the call to it before checking the UDP table.

Once everybody has moved you can change the UDP entries. Follow Stubborne's suggestion and you will not need to be concerned with UDP entries until you are done and there will not be any service disruption to the folks moving. That is one less programming step to be concerned with during the move.
