How to directly migrate from Exchange server 2010 to 2016/2019?

Exchange 2010 migration to Exchange 2019

Steps to Migrate Exchange 2010 to Exchange 2019 Server

Introduction

Microsoft Exchange 2010 has reached the end of its life cycle and support, which means it is prone to bugs, security flaws, and sluggish behavior. Microsoft has released newer versions such as Exchange 2013, 2016, and 2019, but many of us still use Exchange 2010. Exchange server 2019 is more stable and includes new features such as a meta cache database, dynamic database cache to increase cache space for active databases, search indexing, and support for non-English characters in mailboxes. Migrating from 2010 to 2019 usually comes with the caveat that you must first migrate to Exchange version 2013 or 2016, and then to 2019. This is due to the fact that 2010 and 2019 cannot coexist in the same Active Directory but can coexist with the 2013 or 2016 versions, making the intermediate migration time-consuming and complex. However, thanks to EdbMails software, you can perform a direct migration from the 2010 to 2019 versions without requiring intermediate migration hops.

Exchange 2010 to Exchange 2019 Migration

Why should you upgrade the Exchange 2010 version to Exchange 2019?

Exchange 2010 is no longer supported by Microsoft.
Data in the Exchange 2010 tends to be vulnerable to hardware and software issues, corruption, and unauthorized accesses as Microsoft doesn’t support bug fixes and security updates.
Exchange 2019 includes Meta Cache Database (MCDB) functionality.
Support for non-English characters to email addresses with EAI proxy to accepted domains.
Calendar features are updated with ‘Do not forward’, ‘Out of Office’, and other management provisions in Exchange 2019.
Exchange 2019 can be installed in Windows Server Core.
Exchange 2019 provides more cache memory for the active database.
Search Index for a mailbox is in the mailbox only instead in the database.

Pre-migration activities

Before migration ensure source and destination Exchange environments are ready and you meet the system requirements.

Step 1: Prepare a clean destination Exchange environment
Based on your Destination Exchange server version, click on the below link accordingly
Step 2: Create a forest trust (optional)
Know how to create a forest trust on Windows Server 2008
This process will most likely reveal if there are any issues, otherwise you have to fix during migration.
Note: Creating a trust relationship is not required for SBS based environments.
Step 3: Configuration send and receive connectors
Note: During the Exchange server installation process default receive connector will be created
Step 4: Create domain and mailboxes on the target server
Note: Before migration mailbox-enabled user accounts for each user which are included in the migration should be created on your target server.
- You can migrate domain accounts between the Active Directory forests automatically using Active Directory Migration Tool (ADMT) or you can do it manually by creating the accounts on the target forest.
- You can create mailboxes and the corresponding users automatically mapped during the mailbox mapping.
Step 5: Ensure that the admin account used to connect to the source server belongs to the appropriate Active Directory group and its mailbox is configured.
- Ensure that selected account belongs to the Domain Admins group.
- Ensure that this account has a valid, non-hidden mailbox on the source Exchange server.
Step 6: Confirm the Admin account configuration and rights that will be used to connect to the Source and target server
1. Make sure the following roles are assigned to the target admin account
  - ApplicationImpersonation rights
  - View-Only Recipients rights
  - View-Only Configuration rights
  - Assigned mailboxes to the Public Folders
2. Verify the access to the Exchange server's service using IP or Domain Name
  https://[Exchange_IP]/EWS/Exchange.asmx or
  https://[Exchange_Name]/EWS/Exchange.asmx
3. If a client connects from outside the local network then client required to have external URL configured correctly:
  - Open the Exchange Management Shell on the target or source server and verify if the ExternalUrl is defined:
    Command: Copy & Paste it on PowerShell
    Get-WebServicesVirtualDirectory | fl
  - If there's no address in the ExternalUrl line it needs to be defined. Execute the following script:
    Command: Copy & Paste it on PowerShell
    Get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -ExternalUrl https://[Target server's internet name]/EWS/Exchange.asmx
Step 7: Configure the maximum size limit of sent mail and throttling settings
- To speed up the migration process, change the throttling settings on target Exchange
- To allow migration of big items, change message size limits on target Exchange.
Step 8: Install EdbMails Exchange Migration
a. Download and install EdbMails on your computer. Download
b. Double click the EdbMails setup (EdbMailsSetup.exe) to install the application.
