Abstract

In the migration method of the invention, for each migration request (MR) recorded in a migration control server (MCS), the following steps are performed in succession: a second mailbox (BOX2) is created in an electronic messaging service system (S2), the first access address (AD1) of the first mailbox (BOX1) that is to migrate from a first messaging service system (S1) is formed as the access electronic address giving access to the users from the outside for the second mailbox (BOX2), and the physical electronic address (ADP1) recorded for the mailbox (BOX1) is changed, in a directory database (DIR), into the physical electronic address (ADP2) of the mailbox (BOX2).

9. The migration method according to claim 7, wherein prior to processing migration requests, a choice is made between an operating mode with said verifications for executing the third step and an operating mode without said verifications for executing the third step.

10. The migration method according to claim 1, wherein the second electronic messaging service system is connected to a data migration server and, after the fifth step is executed for the first mailbox, a data transfer step is executed, during which the data migration server triggers transfer of data present in the first electronic messaging service mailbox of the first electronic messaging service system to the second electronic messaging service mailbox of the second electronic messaging service system.

11. The migration method according to claim 10, wherein the migration control server records in its database an address migration identifier which identifies address migration performed for the first electronic messaging service mailbox for which the fifth step has been performed, the data transfer step being performed by the data migration server for the first electronic messaging service mailboxes associated with the address migration identifier which identifies the address migration performed in the database of the migration control server.

12.
