Mailbox migration requires account creation, data transfer and a coordinated MX change.
Applies to: Website and email migrations
A safe migration separates data transfer from DNS cutover. Copy and test first, lower risk at the change window, then keep the old service intact until website, email and background tasks have been verified.
Before you start
- Sign in to the Customer Portal and open the affected hosting service.
- Take a current backup before changing website files, databases, DNS or application configuration.
Step-by-step
- Create destination mailboxes and aliases.
- Record current mailbox sizes and credentials. Do not include the secret in a ticket, email or screenshot.
- Copy mail using a supported migration method.
- Change MX records and keep the source available during propagation.
- Reconfigure devices and verify send/receive.
Common problems
| Symptom | Likely cause | What to do |
|---|---|---|
| Receiving works but sending fails. | SMTP authentication, the outgoing hostname, port or encryption mode is incorrect. | Use the full email address as the username and the exact secure SMTP settings supplied for the hosting service; do not use unauthenticated port 25 from a mail client. |
| The same mailbox works in webmail but not on one device. | The mailbox is healthy and the fault is in the device profile, saved password, certificate warning or local network. | Remove only the affected account profile after recording settings, then add it again with IMAP so server mail is not deleted. |
| The restored site opens but behaves incorrectly. | Files and database were restored from different times, cached data is stale or configuration still points to the old location. | Align the restore points, clear application caches and verify URLs, credentials and scheduled tasks before declaring recovery complete. |
| Recent data is missing. | The selected recovery point predates the change or the data was stored outside the backed-up location. | Stop making further changes, identify the required timestamp and ask support what recovery points remain available. |
Important notes
- Mailbox storage is part of the hosting plan's total storage allowance. Removing a device profile does not increase server quota, and POP settings can remove messages from the server.
When to contact Tudor Internet
Open a ticket through the Customer Portal when the checks above do not resolve the issue, when an action is unavailable for your service, or when continuing could risk data loss or service interruption. Include the following so the request can be investigated efficiently:
- The affected domain and SiteWorx account
- The exact error text and time
- The last change made
- Relevant log lines with passwords and personal data removed
Do not send passwords, private keys, full payment-card details, one-time authentication codes or unredacted identity documents in an ordinary support reply.
