@Javi, I'm preparing to move from Polisy to EISY and was curious to know if my UD Mobile customizations will go along with the IP change without programming effort or am I basically starting over?

I have done a UDM backup so I assume I can apply the backup and recover if necessary.

Thanks!

Most customizations should remain intact if the UUID is cleared in UDM (see link below) and the new Credentials (IP address, remote URL, and auth) replace the existing credentials. 

The node-address + SQL-Controller-Table-Base-Column-ID (as UDM supports multiple controllers) are the unique identifiers.  The controller SQL-Controller-Table-Base-Column-ID is tied to the UUID however the UUID is not part of the Unique identifier.  UD Mobile allows users to "clear" the UUID so the SQL-Controller-Table-Base-Column-ID remains intact when the UUID is cleared. UD Mobile will add the new UUID to the existing SQL-Controller-Table-Base-Column on Synchronization if the UUID is cleared.

At a higher level if the node-address does not change then customizations will remain intact.  If synchronization prompts to "remove cached values" after replacing the UUID then create a backup before removing cached values. If customizations/favorites are removed restore the backup then adjust any customizations which were removed to point to the new node-address before synchronization again. 

Insteon should be safe in most situations, other protocols/node-servers have enumerated node-addresses so they are susceptible to Address change. So keep node servers in the same slot and add all required parameters prior to synchronizing UDM.

@Javi I did the migration to the new EISY, the linked procedure for the new controller and UD Mobile was 100% perfect.

Thanks!👍
