Replace the domain name for synced users

This page is for Directory Sync. If you’re using Google Cloud Directory Sync (GCDS), go to GCDS. Directory Sync is currently in public beta.

Using Directory Sync, you can automatically replace the domain name for synced users and groups in your Google cloud directory. If you do, following a sync, your synced Google users and groups have a different domain name than the domain used in your external directory. You can specify whether you want the domain change to occur for newly synced users and groups or new and previously synced users and groups.

Before you begin

Ensure that your new domain is verified in the Google Admin console. For details, go to Verify your domain.
