Impact of Notes User Renaming/Recertifing on Blackberry User/Device

Hello,I would like to know which activities must be done on the BlackBerry Environment (Enterprice Server / User Device) for a notes user that has been renamed or recertified.

P.S:

BlackBerry Enterprice Server: 4.1.316

Domino Server: 7.0.1 FP1

Users: 211

Thanks.
