LS Suite Email Migration Tool

Overview

The LS Suite Email Migration Tool allows you to easily transfer your email messages from your old server or provider to LS Suite.
It works for both single account migrations and bulk migrations (via CSV upload) directly from your LS Suite client area.

This tool:

  • Transfers all your messages from your old server.
  • Preserves the folder and subfolder structure from the source account.
  • Supports a scheduled second run to capture any messages received during the migration process.

For a smooth experience, ensure your current email service supports IMAP access.

Migration Types

You can choose between:

  1. Single Account Migration – migrate one email account by entering its credentials.
  2. Bulk Migration – migrate multiple email accounts at once by uploading a CSV file in the required format.

Performing a Single Account Migration

  1. Go to your LS Suite service page in the Client Area.
  2. Under Management, click Migration Tools.
  3. Click New MigrationSingle Account.
  4. Select your Source Server Type (e.g., Standard SSL, Gmail, Office 365).
  5. Enter the Destination Email (already hosted on LS Suite).
  6. Fill in:
    • Source Server (e.g., imap.example.com or IP)
    • Source Username (often the full email address)
    • Source Password
  7. Click Submit Migration.

Performing a Bulk Migration

Bulk migration lets you move multiple accounts at once.

Steps:

  1. Click New MigrationBulk Migration.
  2. Select your Source Server Type.
  3. Prepare a CSV file in the exact format:
    • email@local – The LS Suite destination email.
    • remote-server – IMAP server of your old provider.
    • username – Username for the source account (can be the email address).
    • password – Password for the source account.
    • masteruser – Optional; used only if your old server supports IMAP Master User authentication.
    • from_date – Optional; migrate only messages after this date (YYYY-MM-DD).
  4. No headers should be included.
  5. Upload the CSV file.
  6. Click Submit Migration.
email@local;remote-server;username;password;masteruser;from_date

Tip: You can download a Sample CSV from the migration page.

Migration Scheduling

When creating a migration:

  • First Execution – Runs the initial transfer of all messages.
  • Second Execution – Recommended after updating your MX records to LS Suite. This captures any new messages received on the old server between the first and second run.

Changing MX Records

To avoid email loss:

  1. Perform the first migration.
  2. Update your domain’s MX records to LS Suite once the first run completes.
  3. Run the second migration to capture any missed emails.

Limitations

  • Trash, Spam, and Junk folders are not migrated.
  • Messages larger than 50MB are not transferred.
  • Maximum 500 accounts per CSV file.
  • Up to 5 migrations can be scheduled at the same time.

Managing Migrations

  • View Progress – See your migration list with status, type, number of accounts, and execution times.
  • Logs – Access logs for each migration to check results or errors.
  • Delete – Cancel a scheduled migration (not possible if it’s already running).

Common Errors & Fixes

  • Authentication failed – Check username/password and IMAP server settings.
  • IMAP not supported – Ensure your old provider supports IMAP access.
  • Incorrect server – Use the server’s IP if the hostname doesn’t work.

After a successful migration, you will receive an email notification containing a summary report of the migration results.
