Dear All,After a crash during the upgrade from CUCM 12.0 to 12.5(SU8), the Publisher needs rebuilding. The backup TAR file isn't detected in DRS for restoration, so a temporary export file was used. Currently, phones are registered to the Subscriber. I'm considering exporting data from the Subscriber, installing a new Publisher, and importing the Subscriber backup file. Will this approach work, ensuring the phones retain their old ITL files and remain registered to the new node?
