Welcome! If you're here, you've likely registered through the Stellar Migrator for Exchange website and received an email containing your login credentials. This email includes a download link for the Stellar Migrator for Exchange software (EXE) and access details for the Licensing Portal (stellarlicenseserver.com). To get started, click on the download link provided in the email or access it directly from the Licensing Portal.
After downloading the Stellar Migrator for Exchange setup file, run the installer and follow the on-screen instructions to complete the installation. Once installed, launch the software — no additional configuration is required. You're now ready to start your test migration using the 2 free mailbox credits included. The next step is to create your first migration job.
When prompted, the 'Login to Licensing Server' window will appear. The Licensing Server URL (https://api.stellarlicenseserver.com) is pre-filled. Enter your User ID and Password. The screen displays License Available count and a green 'Status: Connected' indicator once successfully authenticated. Click OK to proceed with the licensed migration.
When you launch the software and create a new job, the Migration Type screen appears first. Under 'Choose a source server type you want to migrate from', select Exchange Server and enter the source Domain Name. Under 'Choose a target server type you want to migrate to', select Exchange Server and enter the target Domain Name. This configures the job as an Exchange to Exchange (server-to-server) migration. Click Next to proceed.
Provide a name for your migration job (for example, 'Exc to Exc') — this name will be displayed on the list of jobs. Then select the mailbox type(s) you want to migrate: primary/shared mailboxes, archive mailboxes, or public folders. You can also import a pre-mapped CSV file directly from this screen.
Connect the software to the source Exchange Server. Enable 'Use Autodiscover Email' and enter the Email address and Password — the software will automatically locate and connect to the source server. Alternatively, uncheck Autodiscover and manually enter the IP address/FQDN, Email address, and Password. You can also click 'Click here' to reuse the previously used Source ID. Click Validate to confirm the connection before proceeding.
Note: Impersonate Rights are mandatory for the email address used to connect to the Exchange Server.
The next screen displays the list of mailboxes found in the source Exchange Server. Review the list to confirm all required source mailboxes are present. If you have more than 99 mailboxes, use the 'Load Mailboxes Using CSV' option and upload a CSV file containing all mailbox addresses.
Connect the software to the target Exchange Server. Enable 'Use Autodiscover Email' and enter the Email address and Password — the software will automatically locate and connect to the target server. Alternatively, uncheck Autodiscover and manually enter the IP address/FQDN, Email address, and Password. You can click 'Click here' to reuse the previously used Target ID. Click Validate to confirm the connection before proceeding.
Note: Impersonate Rights are mandatory for the email address used to connect to the Exchange Server.
The next screen displays the list of mailboxes found in the target Exchange Server. Review the list to ensure all destination mailboxes are available for mapping. If you have more than 100 mailboxes, use the 'Load Mailboxes Using CSV' option to load the complete list.
The software automatically maps source and target mailboxes by comparing their email addresses. Mailboxes that are successfully matched appear in green; unmatched mailboxes are marked 'Not Mapped' in red. Use the Edit (…) button to manually map any unmatched mailboxes. The status bar at the bottom shows Total mailboxes, Mapped count, and Not mapped count.
Configure when the migration job should run. Choose 'Run manually' to start migration on demand, or select 'Schedule job' and click the Scheduler button to set the frequency (Run once, Daily, Weekly, or Monthly), start and end times, and duration. The description field at the bottom previews the configured schedule. Use the Scheduler dialog to set the exact frequency, occurrence times, start date, and optional end date for the migration run.
Apply a date filter to control which mail items are migrated (applies to mail items only). Options include: Migrate all items, Migrate items older than a specific date, Migrate items not older than a specific date, or Migrate only items from a specific date range. This helps reduce migration scope when needed.
Select the folder types to include in the migration. Available folder types are: Emails, Contacts, Calendars, Tasks, Notes, and Journals. Special folders include Junk Email, Deleted Items, and Drafts. All are selected by default. Uncheck any folders you want to exclude to ensure only the required data is migrated.
Configure migration speed and resilience. Set the number of Concurrent mailbox migration threads (5 recommended), Concurrent item migration threads per mailbox (5 recommended), and the number of retry attempts in case of network failure (default: 2). Migration speed depends on system configuration, network speed, and source and destination server performance.
Review the complete job summary before starting migration. The summary displays: Job name, Mailbox types, Source server (Exchange Server), Target server (Exchange Server), Total mailboxes, Mapped counts for primary/archive mailboxes and public folders, Scheduler setting, Date filter, Folder type filter, and Concurrent mailboxes. If any setting needs correction, click the relevant section in the left panel to go back and edit it. Click Finish to create the migration job.
After clicking Finish to create the job, click Start in the JOB ribbon at the top to begin the migration process. The migration dashboard shows real-time Job Progress with columns for Action, Source mailbox, Target mailbox, Migration progress (%), Total items, Migrated, Filtered, Failed, and Start date. The Mailbox Progress panel at the bottom shows folder-level detail. You can Pause or Stop the migration at any time using the buttons in the JOB ribbon.
After completing the migration, the action field in the job progress section will change from Migrate to Don't Migrate. If the job fails to migrate, it will remain in the Migrate state, allowing you to attempt the migration again without making repeated changes.

The screen displays the License Available count and a green 'Status: Connected' indicator once successfully authenticated. Click OK to proceed and consume licenses for the migration.
When you launch the software and create a new job, the Migration Type screen appears first. Under 'Choose a source server type you want to migrate from', select Microsoft 365. Under 'Choose a target server type you want to migrate to', also select Microsoft 365. This configures the job as an Office 365 to Office 365 (tenant-to-tenant) migration. Click Next to proceed.
Configuring General Settings is the first step in creating a migration job. Start by providing a name for your migration job, such as “365 to 365,” which will appear in the list of migration jobs for easy identification. Next, select the mailbox type(s) you want to migrate, including primary/shared mailboxes, archive mailboxes, and public folders. If you already have a CSV file containing mapped source and target mailboxes, you can enable the option “Migrate using CSV containing the list of already mapped source and target mailboxes” and click Import to upload the file, which allows you to skip the automatic mapping process.
The Connect Source screen provides two registration methods for the source Microsoft 365 tenant: Auto Registration and Manual Registration. With Auto Registration, click “Log in as Microsoft 365 Global admin” to sign in through the Microsoft 365 login window, after which a green checkmark confirms the connection. For Manual Registration, register an application in Azure AD and enter the Email Address, Application (client) ID, Directory (tenant) ID, and Client Secret Value.
The next screen displays the list of mailboxes found in the source Microsoft 365 tenant. The total number of primary mailboxes detected is shown above the list. Review the list to confirm all required source mailboxes are present. If you have more than the displayed mailbox limit, use the 'Load Mailboxes Using CSV' button and upload a CSV file containing all mailbox addresses to load the complete list.
Connect the software to the target Microsoft 365 tenant using the same ADAL and OAuth 2.0 based modern authentication process. With Auto Registration selected, click “Log in as Microsoft 365 Global admin” and sign in using the target tenant’s Global Admin credentials. The Auto App Registration – Target dialog displays the verification steps, and once all steps are completed successfully with green checkmarks, click OK. Alternatively, use Manual Registration by entering the Email Address, Application (client) ID, Directory (tenant) ID, and Client Secret Value for the target tenant’s Azure AD application.
After successfully connecting to the target Microsoft 365 tenant, the next screen shows the list of mailboxes found in the destination tenant. Review the list to ensure all required target mailboxes are available for mapping. If you cannot see all your target mailboxes, use the 'Load Mailboxes Using CSV' option to load the complete list from a CSV file.
The software automatically maps source and target mailboxes by comparing their email addresses. Mailboxes that are successfully matched display the target address in green; unmatched mailboxes are marked 'Not Mapped' in red. Use the Edit (…) button on any row to manually assign a target mailbox to an unmatched source mailbox. The status bar at the bottom shows the total count of mailboxes along with how many are Mapped and Not mapped.
The Scheduler step lets you configure when the migration job should run. Two options are available:
• Run manually – Start the migration on demand by clicking Start in the JOB ribbon.
• Schedule job – Click the Scheduler button to set the frequency (Run once, Daily, Weekly, or Monthly), the occurrence start and end times, and the start date. The Description field at the bottom previews the configured schedule in plain language.
Apply a date filter to control which mail items are included in the migration (applies to mail items only). Choose one of the following options:
• Migrate all items – No date restriction; all mail items are migrated.
• Migrate items older than – Only items before the selected date are migrated.
• Migrate items not older than – Only items from the selected date onwards are migrated.
• Migrate only items from – Migrate items within a specific date range (from date to date).
Select the folder types to include in the migration. By default, all folder types are selected, including Emails, Contacts, Calendars, Tasks, Notes, Journals, Junk Email, Deleted Items, and Drafts. You can uncheck any folders you want to exclude so that only the required data is migrated.
Configure migration performance and resilience settings. Adjust the following parameters based on your system and network capacity:
• Concurrent mailbox migration threads – Number of mailboxes migrated simultaneously (5 recommended).
• Concurrent item migration threads per mailbox – Number of items migrated in parallel per mailbox (5 recommended).
• In case of network failure, rerun job – Number of automatic retry attempts if the migration is interrupted (default: 2).
Note: Migration speed depends on system configuration, network speed, and the performance of both the source and target Microsoft 365 tenants.
Review the complete job summary before starting the migration and verify that all settings are correct before clicking Finish. The summary includes details such as the job name, selected mailbox types, source and target Microsoft 365 tenants, total mailboxes, mapped counts for primary/archive mailboxes and public folders, scheduler settings, date and folder type filters, and the number of concurrent mailboxes. If any setting needs to be changed, use the relevant section in the left navigation panel to go back and edit it. Once everything is verified, click Finish to create the migration job.
After clicking Finish to create the job, click Start in the JOB ribbon at the top of the main window to begin the migration process. The migration dashboard displays real-time job progress, including the current action, source and target mailbox details, migration status percentage, total items, migrated, filtered, and failed items, along with the start and end dates. The Mailbox Progress panel at the bottom provides folder-level migration details, and you can pause or stop the migration at any time using the corresponding buttons in the JOB ribbon.
After the migration completes successfully, the Action field in the Job Progress section changes from 'Migrate' to 'Don't Migrate' for each completed mailbox, indicating that those mailboxes have been fully migrated. If a mailbox fails to migrate, it remains in the 'Migrate' state, allowing you to retry the migration for that mailbox without reconfiguring the entire job or making repeated changes to other mailboxes.
