General

The Smooth Migration or stepwise migration feature can be used for customers who want to migrate a large system (or ‘merge’ a network of systems into fewer systems) and at the same time do a complete hardware refresh, e.g. when moving from Mitel TSW/MD110(s) to a new MiVoice MX-ONE Service Node.

The smooth migration provides a method to migrate/upgrade by moving smaller groups of users in controlled steps instead of a Big Bang method from the old system to the new MX-ONE system. The function was available from MX-ONE 5.0 SP1.

Furthermore, most of the manual labor can be done during office hours.

We recommend that the customer at the same time replaces analog and digital hand­sets, as such a change avoids re-cabling in the MDF for moving users.

The following figure depicts the smooth migration from an MD110/TSW system to an MX-ONE. Here a simple replacement of HW, without any merge of several old systems or change of the number of extensions.
