Step-by-Step Complete Guide to Migrate Exchange 2010 to 2016 Seamlessly
Overview: This article covers a detailed explanation of how you can migrate Exchange 2010 to 2016 in a step-by-step process. Not just the migration process, it has also explained the pre-migration steps that you need to complete before the migration to ensure the process is effortless.
As Exchange Server 2010 support ended on October 13, 2020, many organizations have upgraded their Exchange Server to the latest version. Now, there is an option to either migrate to Exchange 2016 or Exchange 2019 as these are the most preferred Exchange Servers by administrators.
If you haven’t upgraded to the updated Exchange Server and are looking for a way to migrate Exchange 2010 to 2016, this write-up is for you. Here, you will get all the detailed steps on how you can carry out the migration process in a seamless manner.
There are two ways in which a user can migrate Exchange Server 2010 to 2016 i.e. a manual solution and an automated way. First, let’s discuss the manual way in a step-by-step manner.
Pre-requisite & Setup Before Migrating from Exchange 2010 to 2016
You might find these steps a bit lengthy and technical but if you follow the below steps carefully, then you can easily perform this task safely.
- Step 1. Exchange Server Sizing
- Step 2. Fulfill Exchange Server Requirements
- Step 3. Exchange Server Installation
- Step 4. Exchange Server Configuration
- Step 5. Creating Co-existence of Exchange Servers
- Step 6. Exchange 2010 to 2016 Mailbox Migration
Step 1. Exchange Server Sizing
As you are already running Exchange Server 2010, you might have an idea of the performance of the existing server. So, you can consider increasing the RAM, Disk Space, and Processor to ensure smooth working on the new Exchange 2016 Server.
You can also consider reducing or increasing mailbox quotas and ensuring you have enough storage space for mailbox and backup storage.
Furthermore, you can also give thought to separating Exchange logs, Exchange database, and Windows volume.
Step 2. Comply with Exchange Server Requirements
It is necessary to have the right set of resources to set up a new Exchange Server and migrate Exchange 2010 to Exchange 2016.
- Windows Server 2012 onwards
- No less than .Net 4.5.2 (The latest version is recommended)
- Exchange 2010 Server must be updated to SP3 – Update Rollup 11
- Outlook 2010 SP2 with KB2965295 and KB2956191
- Functional AD 2008 or above
Once you fulfill all these requirements, you can now proceed with the Exchange 2016 installation.
Step 3. Exchange Server 2016 Installation
Now download the latest Exchange 2016 version and implement the following steps:
1. First change the directory to the Exchange’s download location.
2. Prepare AD Schema
setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms
3. Now update Active Directory with new Exchange objects
setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms
4. The next step involves domain preparation (You must perform this for all your domains)
setup.exe /PrepareDomain /IAcceptExchangeServerLicenseTerms
Network and directory server requirements for Exchange 2016:
| Component | Requirement |
| Domain Controllers | All forest domain controllers should operate on any one of these Windows Server versions:
|
| Active Directory Forest | The forest’s Active Directory functional level must be Windows Server 2008 R2 or higher |
| Active Directory Site | An Exchange Server installation requires at least one writable domain controller acting as a global catalog server in the Active Directory site. The absence of this will lead to installation failure. Additionally, installing Exchange and subsequently removing the domain controller from the site is not permissible. |
| DNS Namespace Support | Exchange 2016 supports the following domain name system (DNS) namespaces:
For more details on supported DNS namespaces, refer to Microsoft Knowledge Base article 2269838, titled “Microsoft Exchange compatibility with Single Label Domains, Disjoined Namespaces, and Discontiguous Namespaces. |
| IPv6 Support | Pv6 is supported in Exchange 2016 only when IPv4 is installed and enabled. In scenarios where both IPv4 and IPv6 are supported by the network, Exchange servers can communicate with devices, servers, and clients using IPv6 addresses alongside IPv4. For additional information, refer to the article on IPv6 Support in Exchange 2013. |
Once, you fulfill all the above pre-requisites, then you can move to the next step.
5. Install Exchange 2016 on this Server
setup.exe /Mode:Install /Roles:Mailbox /IAcceptExchangeServerLicenseTerms
6. Finally, reboot the server.
Another step for Exchange 2010 to 2016 migration is completed here. Now, go through the next section to proceed further.
Step 4. Exchange Server Configuration
1. Now log in to ECP to test that everything is running fine. For this, open a browser and type
https://servername/ECP.
2. Update the Service Connection Point in the Active Directory. Also, ensure that the Server Connection points to your existing autodiscover URL.
Eg. – autodiscover.domain.com/autodiscover/autodiscover.xml
Afterward, we will point this name to the New Exchange 2016 Server.
3. Export your public SSL from the old Exchange Server and Import it into the new Exchange Server.
4. Now restart IIS to apply the new SSL certificate.
iisreset /noforce
5. Open EMS on your machine and run the following script to update all virtual directory URLs. Once all these steps are performed, you can proceed for Exchange 2010 to Exchange 2016 migration.
$Server = “ServerName” $HTTPS_FQDN = “mail.domain.com” Get-OWAVirtualDirectory - Server $Server | Set-OWAVirtualDirectory - InternalURL “https:// $( $HTTPS_FQDN ) /owa” -ExternalURL “https:// $( $HTTPS_FQDN ) /owa” Get-ECPVirtualDirectory -Server $Server | Set-ECPVirtualDirectory - InternalURL “https:// $( $HTTPS_FQDN ) /ecp” -ExternalURL “https:// $( $HTTPS_FQDN ) /ecp” Get-OABVirtualDirectory -Server $Server | Set-OABVirtualDirectory - InternalURL “https:// $( $HTTPS_FQDN ) /oab” -ExternalURL “https:// $( $HTTPS_FQDN ) /oab” Get-ActiveSyncVirtualDirectory -Server $Server | Set- ActiveSyncVirtualDirectory -InternalURL “https:// $( $HTTPS_FQDN ) /Microsoft-Server-ActiveSync” -ExternalURL “https:// $( $HTTPS_FQDN ) /Microsoft-Server-ActiveSync” Get-WebServicesVirtualDirectory -Server $Server | Set- WebServicesVirtualDirectory -InternalURL “https:// $( $HTTPS_FQDN ) /EWS/Exchange.asmx” -ExternalURL “https:// $( $HTTPS_FQDN ) /EWS/Exchange.asmx” Get-MapiVirtualDirectory -Server $Server | Set-MapiVirtualDirectory - InternalURL “https:// $( $HTTPS_FQDN ) /mapi” -ExternalURL https:// $( $HTTPS_FQDN ) /mapi
6. Finally, review the Exchange DB settings and ensure that you create DBs according to the disk configuration and requirements.

Step 5. Co-Existence Setup
Now it’s time to link the new server to the old one.
- Point all the external DNS records for emails to the new server and update all firewall rules (if any). (The emails will now flow into the new Exchange Server and then to the old one).
- Remove ExternalURL Value from the previous server.
- Point all the Internal Exchange Records related to emails to the new server.

Step 13. You can then open the migration tab to check the migration status by selecting that batch.
After completion of the migration process, it is time to decommission the Exchange 2010 Server. For that, you need to take care of the following points:
- The router is pointing to the new Exchange Server after the Exchange 2010 to Exchange 2016 migration.
- Point the external domain DNS to the new server. (If you have an external IP Address for the server)
- Point scanners and multi-function printers to the new server.
Once you have performed all these actions, you can perform the decommissioning process very smoothly.
