After you get a clean report from the migration readiness check, move your Lightning Sync settings to Einstein Activity Capture. Accept the terms of service agreement and start your move. If you need more time to prepare, you can pause your migration and return to this step later. If you connect to Salesforce using Google, before you start your move, work with your Google admin to give the service account access to your Google users’ data.

Remember that your users can notice a pause in contact and event sync while we move settings, but users can continue working as usual. The migration tool ensures that no contact or event changes are lost during the transition. Any items that were updated in the interim sync after your settings are moved. Depending on the complexity of your configurations, the move could take some time.
For a reminder of what specifically is moved, see How Does the Lightning Sync Migration Tool Work?
There’s no button for reverting to Lightning Sync after you’ve started moving your settings. But don’t worry: If you’re not feeling ready, you can cancel the tool for now and return at any time.

If you connect to Salesforce using Google, Salesforce provides a service account for you.
You don’t need your Lightning Sync Google project or service account. Work with your Google
admin to give the service account domain-wide authority and access to your users’ Google data.
When prompted, copy the service account client ID and comma-delimited list of the OAuth scopes
from the tool. Then, navigate to your Google Admin Console and add the service account
client ID and OAuth scopes to your Google Workspace environment. See the Google documentation about delegating domain-wide authority to
a service account.
We recommend that you keep your Lightning Sync Google project and service account active during the migration process. After you turn off Lightning Sync, you can delete your Google project and service account.
- Accept the terms of service agreement for Einstein Activity Capture when ready. Then click Next. If you connect to Salesforce using Microsoft, you see the terms of service agreement after the readiness check.
