Exchange 2010 to 2019 migration

Over the years, Microsoft has introduced newer and more advanced versions of Exchange Server, phasing out older editions like Exchange 2003, 2007, and 2010. With Exchange 2010 no longer supported, organizations using it face security risks, compliance issues, and outdated performance. To maintain a secure and reliable IT environment, upgrading to Exchange 2019 is essential.

EdbMails Exchange Migration software facilitates direct migration from Exchange 2010 to Exchange 2019 without intermediary hops. It supports the transfer of mailboxes, public folders, archive mailboxes, and shared mailboxes from on-premises Exchange servers.

With concurrent migration, multiple mailboxes are processed simultaneously, while incremental (delta) migration transfers only new or modified data, optimizing bandwidth during subsequent migration operations.

Security is maintained through encrypted data transfers and strict access controls. The software automates mailbox creation on the target server, streamlines mailbox mapping, and manages Exchange and Office 365 throttling to ensure uninterrupted operation.

Comprehensive reporting provides visibility into the migration process, helping track progress and resolve issues effectively.

The following section outlines the planning process, prerequisites, step-by-step migration using EdbMails Exchange migration software, post-migration tasks, and key benefits of using EdbMails for Exchange 2010 to 2019 migration.

1. Exchange 2010 to Exchange 2019 migration planning

   Planning is essential to ensure a safe migration of all data to the target server. Here's a general checklist and migration strategy to follow:

   1. Communicate the changes to all users and stakeholders.
   2. Estimate the upgrade costs for hardware, operating systems, and maintenance factors.
   3. Prepare the target environment and ensure sufficient bandwidth for migration.
   4. Make note of inventory items like Active Directory association, operating system, firewall, network configuration, port numbers, installed programs, and list of users.
   5. Install Exchange 2019 and create suitable mailboxes and Public folders.
   6. Perform a test migration on a few mailboxes to ensure readiness for a full migration.
   7. Migrate from Exchange 2010 to 2019 and configure the domains to receive emails.
   8. Create new Outlook profiles for all users and verify email reception.
   9. After verifying and informing all end users, decommission Exchange 2010.

2. Exchange 2010 to 2019 migration prerequisites

   • Step 1: Check that your system meets the Exchange 2019 setup requirements.

     Exchange server version	Coexistence scenario	Requirement	Migration Possible
     Exchange 2019	Exchange 2019 cannot coexist with 2010	Install Cumulative Update 32 for Exchange 2010 SP3	Yes! With EdbMails Exchange migration, you can migrate to any Exchange server version regardless of the coexistence issue

     Note: If you have the Domain Controllers (DC) running on Windows Server 2008, ensure that you first transfer the roles to a DC running Windows 2012 R2 or higher before you decommission any of the earlier DC’s. Exchange 2019 requires Active Directory forest functional level of Windows Server 2012 R2 or higher. See the Exchange server supportability matrix.

   • Step 2: Prepare your system with the following prerequisites for Exchange 2019

     Complete the following prerequisites for Active Directory, Windows 2019 Mailbox server, and Windows 2019 Edge Transport servers for installing Exchange server 2019.

     1. Prerequisites for preparing Active Directory (AD)
     2. Windows Server prerequisites for Exchange 2019
   • Step 3: Decide the migration path for Exchange 2010 to 2019

     Consider whether you prefer a cutover, staged or hybrid migration. EdbMails supports all the migration methods, ensuring zero server downtime or data loss during migration.

     Current environment and requirement	Ideal migration approach	How does the migration take place?
     Exchange 2010 to 2019 migration in a single event and in a limited time frame.	Exchange 2010 to 2019 cutover migration	Set up your target Exchange server and migrate everything in a single sitting. Suitable for large mailbox migration
     You have little time and want to migrate mailboxes in phases or over the weekends	Staged Exchange migration	Migrate your mailbox data in stages. Migrate the most recent data first followed by the others.
     You want to migrate from Exchange 2010 to a Hybrid Exchange 2019 and Office 365 environment	Exchange Hybrid migration	Migrate mailboxes from the source server to a Hybrid Exchange and Office 365 environment. See the prerequisites for migration in hybrid environment.

   • Step 4: Setup the target Exchange Server 2019 for migration

     Following is a list of key points for installing and preparing the Exchange 2019 server for migration.

     1. Prepare Active Directory (AD) and domains
        1. Before you install Exchange Server 2019, 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 must 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 2019

        Ensure that you meet the server system requirements and prerequisites outlined in the preceding sections. Next, install Exchange 2019 mailbox server and edge transport server using the setup wizard.

     3. Prepare a clean Exchange 2019 target environment
        1. Install and upgrade Exchange to the latest Cumulative Update to keep your server up to date.
        2. Create and configure a Send connector to send mail outside the Exchange organization.
        3. By default, Exchange automatically creates receive connectors for inbound mail flow when the mailbox server is installed. However, if you want to configure custom receive connectors for certain mail flow scenarios, follow the steps in the link.
        4. Add accepted domains to allow recipients to send and receive email from another domain.
        5. Configure the default email address policy to add the accepted domain to every recipient in the organization.
        6. 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).
        7. 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.
        8. Configure SSL certificates from a third-party certificate authority for services such as Outlook Anywhere and Exchange ActiveSync.
        9. Verify the Exchange server installation by running the command Get-ExchangeServer on the Exchange Management Shell (EMS)
     4. Create mailboxes and public folder on the target Exchange server
        • EdbMails automatically creates mailboxes on the target Exchange server. If you want to manually create mailboxes refer to the link below.

            Steps to create mailboxes in Exchange server

        • To migrate public folders, ensure to set the admin permissions to each public folder on both source and the target Exchange servers. Also create mail-enabled public folders on the target server.

            Steps to create Public folder in Exchange server

        • Install cumulative updates (CU) on Exchange server 2010

          Ensure that you have installed the latest cumulative updates (CU) on the source for Exchange server 2010 to 2019 migration.

        • 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 the trust in advance, it is possible to address the trust issues during or after the migration.

          Note: This step applies to Windows Server 2008, Windows Server 2008 R2 and Windows Server 2012. Creating a trust relationship is not required for SBS based environments.

        • 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 (2019)

          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.
             3. Organization Management role group. It is an elevated permission that is required to migrate Public folders.
          2. On the target server
             1. ApplicationImpersonation
             2. View-Only Recipients
             3. View-Only Configuration
        • 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. This property also applies to all the other user mailboxes.

        • Configure the throttling and message-size limits

          You can manually change the EWS throttling and message size limits on the target Exchange 2019 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 2019
