  • Step 10

    Connect Target

    Connect the software to the target Exchange Server 2019. Enter the following details:

    • Server Name — e.g., Ex-2019
    • FQDN — e.g., Ex-2019.thestellarmigration.com
    • Domain\Administrator — e.g., thestellarmigration.com\administrator
    • Password — enter the administrator password

    Click Validate to confirm the connection. A green checkmark will appear upon success. Alternatively, click ‘Click here’ to load a previously saved Target ID from the Saved Connections dialog — this allows you to skip re-entering credentials and streamlines the setup process.

    Note: Administrator or impersonation rights are required for the account used to connect to the target Exchange Server.

    Map Mailboxes
  • Step 11

    Target Databases

    The software automatically discovers and displays all mailbox databases found on the target Exchange Server 2019. Verify that the destination database is available and has sufficient storage space to accommodate the migrated data.

    In this example, Mailbox Database 1293277532 is found on Ex-2019 with a size of 40 GB. Click Next to proceed

    Scheduler
  • Step 12

    Map Databases

    The software maps the source database (Exchange Server 2016) to the target database (Exchange Server 2019). The mapping screen displays the source database alongside the available target databases for pairing.

    Review the mapping to ensure the correct source and target databases are paired. If the auto-mapping is incorrect, use the dropdown to select the correct target database for each source database. Click Next once all databases are correctly mapped.

    Date Filter
  • Step 13

    Advance Setting

    Configure the maximum number of concurrent mailboxes allowed during migration. This setting controls how many mailboxes are migrated simultaneously.

    Note that increasing the concurrency does not necessarily improve overall migration speed — performance is primarily dependent on available network bandwidth and server load. The default value is 10 concurrent mailboxes. Adjust as required and click Next to proceed.

    Folder Type Filter
  • Step 14

    Summary

    Review the complete migration job summary before finishing. The summary screen displays all configured settings for the job:

    • Job name
    • Mailbox types selected (Primary, Shared, Archive, Public, Arbitration, AuditLog, Monitoring, Discovery, Resource)
    • Source server — Ex-2016.thestellarmigration.com
    • Target server — Ex-2019.thestellarmigration.com
    • Total databases and Mapped databases
    • Concurrent mailboxes setting

    If any setting requires correction, click the relevant section in the left panel to go back and edit it. Once satisfied, click Finish to create the migration job.

    Max Concurrency
  • Step 15

    Initiate Migration

    After clicking Finish to create the job, the job will appear in the jobs list. Click Start in the JOB ribbon at the top to begin the migration process.

    The migration dashboard shows real-time Job Progress with the following columns:

    • Action — current operation (Migrate / Don’t Migrate)
    • Source mailbox — the mailbox being migrated from
    • Target mailbox — the mailbox being migrated to
    • Migration progress (%) — percentage completion
    • Total items, Migrated, Filtered, and Failed counts
    • Start date — when the mailbox migration began

    The Mailbox Progress panel at the bottom shows folder-level detail for each mailbox being processed. You can Pause or Stop the migration at any time using the buttons in the JOB ribbon.

    Summary
  • Step 16

    Migration Completed

    After completing the migration, the Action field in the Job Progress section will change from ‘Migrate’ to ‘Don’t Migrate’, indicating the job has finished successfully.

    If any mailbox fails to migrate, it will remain in the ‘Migrate’ state, allowing you to retry the failed mailboxes without reconfiguring the entire job. Review the progress report to identify and address any failures before re-running the job.

    Initiate Migration
  • Step 1

    Download the Software

    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.

    Download the Software
  • Step 2

    Install the Software

    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.

    Install the Software
  • Step 3

    Login to Licensing Server

    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.

    Login to Licensing Server
  • Step 4

    Migration Type

    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', select Exchange Server. This configures the job as an Office 365 to Exchange Server migration. Click Next to proceed.

    Migration Type
  • Step 5

    General – Create Migration Job

    Provide a name for your migration job (for example, '365 to Exchange') — 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.

    Create Migration Job
  • Step 6

    Connect Source

    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.

    Auto Registration
  • Step 7

    Connect Source – Auto Registration

    Once all Auto registration steps finish successfully, the dialog shows green checkmarks for all actions performed: Registered the application in Azure AD, Authenticated the application, Connected to Exchange Web Services, and Connected to Microsoft Graph API. The Result section confirms 'Successfully completed'. Click OK to return to the Connect Source screen.

    Source Mailboxes
  • Step 8

    Connect Source – Connection Confirmed

    After successful authentication, a green checkmark appears next to the 'Log in as Microsoft 365 Global admin' button, confirming the source Microsoft 365 tenant is connected.

    Auto Registration
  • Step 9

    Source Mailboxes

    The next screen displays the list of mailboxes found in the source Microsoft 365 tenant. Review the list to confirm all required source mailboxes are present. If you have more mailboxes than the number listed, use the 'Load Mailboxes Using CSV' option and upload a CSV file containing all mailbox addresses.

    Target Mailboxes
  • Step 10

    Connect Target

    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. Click Validate to confirm the connection.

    Note: Impersonate Rights are mandatory for the email address used to connect to the Exchange Server.

    Map Mailboxes
  • Step 11

    Target Mailboxes

    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 mailboxes than the number listed, use the 'Load Mailboxes Using CSV' option to load the complete list.

    Scheduler
  • Step 12

    Map Mailboxes

    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.

    Date Filter
  • Step 13

    Scheduler

    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.

    Folder Type Filter
  • Step 14

    Date Filter

    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.

    Max Concurrency
  • Step 15

    Folder Type Filter

    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.

    Summary
  • Step 16

    Max Concurrency

    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.

    Initiate Migration
  • Step 17

    Summary

    Review the complete job summary before starting migration. The summary displays: Job name, Mailbox types, Source server (Microsoft 365), 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.

    Initiate Migration
  • Step 18

    Initiate Migration

    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.

    Initiate Migration
  • Step 19

    Migration Completed

    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.
