# Prepare for the Lightning Sync Retirement and Migrate to Einstein Activity Capture

Lightning Sync is scheduled to retire in 2027. Migrate to Einstein Activity Capture to continue syncing contacts and events between Microsoft® or Google applications and Salesforce. Use the Lightning Sync migration tool to complete the process.

**Where:** This change applies to all Lightning Sync in Professional, Enterprise, Performance, Unlimited, and Developer editions.

**Who:** All Lightning Sync configurations except those without enough licenses for Einstein Activity Capture or another exemption. Orgs with exemptions won’t see the Lightning Sync migration tool in Setup.

**How:** Follow the multi-step process to complete the migration. First, use the Lighting Sync migration tool in Setup to migrate to Einstein Activity Capture. Then, assign users one of the Einstein Activity Capture permission set licenses. Next, confirm that users are in an active Einstein Activity Capture configuration, and add them if necessary. When you’re ready, turn off Lightning Sync.

You can’t migrate to Einstein Activity Capture with Microsoft Exchange Web Services (EWS) as your authentication method. Upgrade from EWS to Microsoft Graph first.
