Migrate public folders from Exchange 2010 to 2016

Public folders in Microsoft Exchange are essential for sharing information and collaborating within an organization. However, as Exchange 2010 has reached its end of support, migrating public folders to Exchange 2016 has become crucial. Exchange 2016 offers significant improvements in performance, security, and manageability, such as enhanced scalability, streamlined architecture, and better protection features. Additionally, the upgraded Outlook Web Access (OWA) and continued support make Exchange 2016 a more reliable platform, ensuring your organization stays compliant and secure.

To facilitate this migration seamlessly, Exchange migration software provides a comprehensive solution. It simplifies the migration process by ensuring a smooth transfer of public folder data, including emails, calendars, and contacts, while preserving permissions and avoiding downtime. With features like selective migration, incremental migration, and handling large data volumes, EdbMails ensures a smooth migration experience from Exchange 2010 to 2016, allowing organizations to upgrade without disruptions.

The following sections cover the critical steps for migrating public folders from Exchange 2010 to 2016, including migration planning, prerequisites, the migration process, post-migration tasks, and how EdbMails can streamline the entire process for a hassle-free experience.

   • Step 2: Prepare your system with the following prerequisites for Exchange 2016

     Ensure that you meet the following prerequisites for Active Directory, Windows 2016 Mailbox server and Windows 2016 Edge Transport servers.

     1. Prerequisites for preparing Active Directory (AD)
     2. Windows Server prerequisites for Exchange 2016
   • Step 3: Setup the target Exchange Server 2016 for migration

     Given below is a list of key points for installing and preparing the Exchange 2016 server for migration.

     1. Prepare AD and domains
        1. Before installing Exchange Server 2016, you need to prepare your Active Directory forest and its domains for the new version of Exchange.
        2. If you have a separate team to manage the Active Directory schema, you need to first extend the active directory schema, else proceed to the next step to prepare the Active Directory.
        3. If you have multiple domains you need to additionally prepare the Active Directory domains.
     2. Install Exchange server 2016

        Before installing the Exchange server 2016, ensure that you meet the server system requirements and prerequisites as outlined above. Next, follow the link to install Exchange 2016 using the setup wizard.

     3. Prepare a clean Exchange 2016 target environment
        1. Create and configure a Send connector to send mail outside the Exchange organization.
        2. By default, Exchange automatically creates receive connectors for inbound mail flow when the mailbox server is installed. If you need to configure receive connectors, follow the steps in the link.
        3. Add accepted domains to allow recipients to send and receive email from another domain.
        4. Configure the default email address policy to add the accepted domain to every recipient in the organization.
        5. Configure external URLs (domains) on the virtual directories in the Client Access (frontend) services on the Mailbox server to allow clients to connect to your server from the internet (outside the organization’s network).
        6. Configure internal URLs on the virtual directories in the Client Access (frontend) services on the Mailbox server to allow clients to connect to your server from the internal network.
        7. Configure SSL certificates from a third-party certificate authority for services such as Outlook Anywhere and Exchange ActiveSync.
        8. Verify the Exchange server installation by running the command Get-ExchangeServer on the Exchange Management Shell (EMS).
     4. Install cumulative updates (CU) on Exchange server 2010

        For migrating Exchange server 2010 to Exchange 2016, it is required that you have the latest cumulative updates (CU) installed on the source server (2010). A minimum of Exchange 2010 SP3 RU8 or later is required to migrate Public folders.

     5. Create trust relationship between forests (Optional)

        A forest trust is an authentication between two domains within the same Active Directory forest which creates a trust between two root domains for exchanging information. By creating a trust in advance, it is possible to address the trust issues during or after the migration.

     6. Assign management roles to the admin account

        Ensure that you have set the following permissions to the admin account on the source (2010) and target server (2016)

        1. On the source server
           1. ApplicationImpersonation
           2. View-Only Configuration - Run the cmdlet New-ManagementRoleAssignment using the Exchange Management Shell to assign the View-Only Configuration role to the admin.
        2. On the target server
           1. ApplicationImpersonation
           2. View-Only Recipients
           3. View-Only Configuration
     7. Verify the mailbox of the admin account

        Check to see if the admin account that has been assigned management roles has a valid and non-hidden mailbox on the Exchange 2010 server.

     8. Create a Public folder on Exchange 2016

        Ensure that you create a Public folder on the target server and make it mail-enabled before you migrate.

         Create Exchange Public folder and assign mailbox user

     9. Configure the throttling and message-size limits

        You can manually change the EWS throttling and message size limits on the target Exchange 2016 server by following the steps outlined in the links below.

        1. Change the EWS throttling settings on Exchange server
        2. Change message size limits on target Exchange 2016

     Note: To migrate Public folders to Exchange 2016 with EdbMails, you do not require PowerShell scripts. The following steps describe the public migration method by using EdbMails graphical user interface (GUI).

   • Step 3: Connect to source Exchange server 2010

     • Ensure you have set the necessary admin permissions to all the public folders you wish to migrate.
     • In the ‘Connect to Exchange Server (Source)’ window, choose the required connection option. To migrate the public folder, select ‘Connect to Public Folder’ and proceed.

       

        Different methods to connect to Exchange servers

     • Enter the source Exchange 2010 server details and click the ‘Login’ button.

   • Step 4: Select the Exchange 2010 public folders

     • After successfully logging into your source Exchange server, EdbMails automatically displays all the public folders and their subfolders in a tree view in the left pane of the main migration window. You can choose to select all public folders or only the specific ones needed for migration.
     • Next, choose 'Migrate to Live Exchange'.

       

     • During your first migration with EdbMails, it performs a full migration. Subsequent migrations from the same source to the target are incremental migrations, transferring only new or modified data not included in the previous migration. This approach optimizes internet bandwidth and reduces overall migration time.
   • Step 5: Connect to target Exchange server 2016

     Before connecting to your target Exchange 2016 server, ensure that you have created mail-enabled public folders on your target Exchange server and set the necessary admin permissions for all the public folders you wish to migrate. For more details refer to the link below:

       Steps to create Exchange Public folders and assign admin permissions.

     • Select the required connection option. Choose ‘Connect to Public Folder’ to connect to Exchange 2016 public folders.

       

     • Enter target Exchange 2016 server details and then click the ‘Login’ button to proceed.

       

   • Step 6: Exchange 2010 to 2016 public folder mapping

     • Select the required mapping option.

       

     • EdbMails automatically maps public folders between the source and the target servers, reducing the manual effort, optimizing the migration process and conserving valuable time when handling a substantial volume of public folders. You can also manually map source folders to the required target folders and map the source and target folders using a CSV file.

       

     • EdbMails allows you to customize your migration using folder and item filter options. You can migrate data within specific date ranges, exclude certain standard and custom folders, and perform various other customizations.

       

   • Step 8: Start public folder migration from Exchange 2010 to 2016

     After completing the mapping process, enter the job name and initiate the migration. The migration status is displayed on the progress bar. You can also check the migration status using the migration report, which provides details on the total number of migrated emails, folders, and mailbox items.
