To
migrate IMAP email to Google Workspace (formerly G Suite) without losing data, use a structured IMAP migration process. First, ensure IMAP access is enabled on the source email server and verify login credentials. In the Google Admin console, go to Data Migration and select IMAP as the source. Enter the server settings, then choose whether to migrate all mail or specific date ranges. Map users correctly and start a small test migration first. This helps confirm folder structure, labels, and attachments are preserved. Once validated, run the full migration. Avoid deleting source emails until verification is complete. After migration, check Gmail folders, search functionality, and missing items. For large mailboxes, migrate in batches to reduce errors. Using stable internet and monitoring logs ensures no interruptions. Proper planning guarantees a complete, safe transfer with zero data loss successfully ensured today
