Manual Methods to Migrate Kerio Mailbox to Google Workspace or Gmail

2. Go to Settings > See all settings > Accounts and Imports.
3. Click Import mail and contacts.
4. Enter the Kerio email address.
5. Provide POP server details and credentials.

2. Add a Gmail account to the Kerio Connect Client using IMAP.
