The ProVision tool suite, including the Nortel Migration Tool, allows the administrator to migrate either a subset or all of the terminals from CS 1000 into the ProVision database, carry out manipulation of data as needed, and then load the data on the applicable Avaya Aura® servers. ProVision also allows the administrator to replace TNs when collapsing multiple CS 1000 systems into a single Avaya Breeze® platform cluster. After collapsing, the Nortel Migration Tool creates a .csv file for each collapsed CS 1000 containing TN data.
