Business email migration checklist
Following a structured migration process can reduce the risk of downtime and data loss when changing email providers.
- Identify all company domains.
- List existing email accounts.
- Review mailbox sizes.
- Prepare domains in the new platform.
- Create destination mailboxes.
- Test source IMAP connectivity.
- Analyze folders and message counts.
- Migrate or archive historical email.
- Update MX, SPF, DKIM and required DNS records.
- Verify new mail flow and user access.
Change DNS near the end
Changing MX records before the destination environment is fully prepared can create unnecessary disruption.
Keep the old service available temporarily
After DNS cutover, keeping the previous mail system available for a short verification period can help identify any missing messages or folders.
