User Account Migration

Migrate shared contacts
Level of Effort:
Low
You should migrate shared contact information for any users and distribution lists that
you aren’t fully activating in Google Apps during this phase. Doing so allows your
early adopters to see the shared contact information for all users and distribution lists
from within Google Apps.
Note:
During the Global Go Live phase, you’ll migrate your distribution lists into
Google Groups; for now, you’ll simply migrate their shared contact information.

Finish provisioning users

that haven’t been provisioned yet, using the same method you used during the Early
Adopters phase.
Migrate distribution lists into Google Groups
Level of Effort:
Low
