I need to move well over 10,000 messages from my Zoho Mail account into Google Workspace Gmail while keeping every existing folder/label exactly as it is. No contacts or calendar data are involved—just the email and its organization. A smooth, verifiable transfer is essential. IMAP, Google Workspace Migration Tool, Zoho’s export utilities, or another proven method are fine with me as long as the end result meets the following acceptance criteria: • Every message migrates (random spot-checks must show matching counts in Zoho and Gmail). • All folders/labels remain intact and properly mapped in Gmail. • No duplicate or missing items. • A brief hand-over report summarises the steps taken, any scripts or tools used, and where logs/backups are stored for safety. The changeover should cause minimal disruption—I’ll keep Zoho open until you confirm the migration is complete and validated. Let me know your estimated timeframe and any preliminary information you need (login credentials can be shared securely once we start).
