IP Addresses Connected to During IP LockDown

MigrationWiz uses a global geo-distributed migration farm that includes thousands of IP addresses. In some cases, however, network administrators may want to restrict access to a pre-determined set of IP addresses for security reasons. As a result, we offer the ability to lock down a MigrationWiz connector to use only a specific set of IPs.

If an IP LockDown is required, we offer you the option to bind a connector to one of our U.S. data centers or a regional Azure Data Center. It is important to understand the impact on the migration:

  • Migration data traffic will proceed through one of our U.S. data centers or a regional Azure Data Center, depending on what has been selected during project setup. 


  • IP LockDown does not work with BitTitan Autodiscover using MigrationWiz. To add Users to the project, use Bulk Add via a CSV file or add them manually.
  • IP LockDown does not work for Microsoft 365 to Microsoft 365 migrations using coexistence.
  • For projects that use Azure Storage, IP lockdown will not work for your custom Azure Storage unless Microsoft server IPs are included as well. For more details on Microsoft endpoints, refer to URL & IP address ranges.

If you want to use IP LockDown you must:

  1. Set the Advanced Options 
  2. Open  Firewall Ports

These steps are fully described below.

Set Advanced Options for the Project in MigrationWiz

Complete these steps to set the preferred data center and add the support option for IP LockDown:

  1. Sign in to MigrationWiz at http://migrationwiz.bittitan.com/
  2. Access the project dashboard.
  3. Click Edit, and then click Advanced Options.
  4. Select the customer's local region in the Performance section under the Preferred BitTitan Data Center drop-down menu.
  5. In the Support section, add this support option in the Support Options field: Tags=IpLockDown!
  6. Click Save.

Open Firewall Ports

Open firewall ports to allow MigrationWiz to communicate back to BitTitan servers. All migrations need to have the following ports open. 

  • Ports 80 and 443.
  • If migrating from Zimbra, ports 7070 and 7071 will also need to be open.

Add the BitTitan IPs and the IPs for your region's data center from the table below.

These are the IPs that BitTitan uses for support and other communication and should always be enabled when performing a migration.

  • BitTitan Support Server:
  • Endpoint Validation Server:
  • Debug Servers: and

Next, find the data center that is closest to the customer, and open the firewall ports to allow access to the list of IP addresses in that data center (not all data centers have multiple IP addresses). Access is only required for the IPs in your region. For example, if you are in Asia Pacific, you do not need to allow access to the Australian IPs.
