In various embodiments, a device receives profile data regarding users or devices of an on-premise telephony system. The device identifies, based on the profile data, group features associated with the users or devices of the on-premise telephony system. The device forms a candidate set of users or devices of the on-premise telephony system for migration to a cloud-hosted call agent, based on them sharing at least one of the group features. The device provides data indictive of the candidate set of users or devices to a user interface for display.
