Exchange Server 2016 Migration to Exchange 2019

In this article of Exchange Server 2016 Migration to Exchange 2019 by “Techijack”

We will dig deep into every important step that is mandatory for the migration process to avoid errors

Therefore, Migrating Exchange 2016 to Microsoft Exchange 2019

We have to create a co-existing environment between Exchange 2016 and 2019

So, we will install Exchange Server 2019 to our existing organization and then we will start the migration process to move all the configurations, certificates, and Mailboxes to our new Mailbox Server

Once we complete all the configuration settings on a new Microsoft Exchange Server 2019

We will then decommission our old Exchange Server 2016 and will check the mail flow functionality with the new Server

Before we start our migration of Exchange 2016 to 2019

Let’s get familiar with the existing scenario of the Techijack organization

 

Current Exchange 2016 Environment For Techijack Organization

Techijack Organization has a single Active Directory Server on Windows Server 2016 with a single Exchange Server 2016 CU 22

Forest and Domain functional level is Windows Server 2016

The current Server is fully functional with a perfect mail flow internal and external

Also, Public DNS for the old Exchange is configured and working properly.

Exchange Server 2016 is installed on a Hyper V with proper hardware configuration

DC Name = DC01, Exchange 2016 Name = EX01, Exchange 2016 Database Name = DB01

Namespace we are using for the Techijack organization is mail.techijack.live

 

Microsoft Exchange Server Migration from 2016 to 2019

As we already have a working Exchange Server, so let’s begin with Migration

So, we will create a new virtual machine and will install a new windows server 2019 on it

We will rename a new windows server 2019 as EX02-2019 and will provide the IP Address and DNS settings.

Also, we will update the new server with windows server updates

So, Now its time to install the Exchange 2019 prerequisites on the new EX02-2019 & Active Directory Server

Following software is required to install on AD server as well

  • Net Framework 4.8
  • Visual c++ Redistributable Package for Visual Studio 2012
  • Visual c++ Redistributable Package for Visual Studio 2013
  • Remote Tool Administration Pack
  • Powershell Cmdlet to install Remote Tool AD is: Install-WindowsFeature RSAT-ADDS

  • Visual c++ Redistributable Package for Visual Studio 2012
  • Visual c++ Redistributable Package for Visual Studio 2013
  • Microsoft Unified Communications Managed API 4.0
  • URL Rewrite 2.1
  • Also, you need to install Lync and skype for business components (below is a cmdlet to install this component)
  • Powershell Cmdlet: Install-WindowsFeature Server Media-Foundation
  • Install-WindowsFeature Server-Media-Foundation, NET-Framework-45-Features, RPC-over-HTTP-proxy, RSAT-Clustering, RSAT-Clustering-CmdInterface, RSAT-Clustering-Mgmt, RSAT-Clustering-PowerShell, WAS-Process-Model, Web-Asp-Net45, Web-Basic-Auth, Web-Client-Auth, Web-Digest-Auth, Web-Dir-Browsing, Web-Dyn-Compression, Web-Http-Errors, Web-Http-Logging, Web-Http-Redirect, Web-Http-Tracing, Web-ISAPI-Ext, Web-ISAPI-Filter, Web-Lgcy-Mgmt-Console, Web-Metabase, Web-Mgmt-Console, Web-Mgmt-Service, Web-Net-Ext45, Web-Request-Monitor, Web-Server, Web-Stat-Compression, Web-Static-Content, Web-Windows-Auth, Web-WMI, Windows-Identity-Foundation, RSAT-ADDS

After completing the above prerequisites for exchange 2019, now we are good to install the latest Exchange 2019

Moreover, we have to extend the Schema, prepare AD and Domain before we run Exchange Server 2019 setup

Now install Microsoft Exchange Server 2019 and select Mailbox Role

Installing-Mailbox-Role-Exchange-2019

Complete the Installation on New Exchange Server 2019 (EX02-2019)

Completing Exchange Setup

After installing the Exchange 2019 on Ex02-2019 restart the server and open Exchange Admin Center to confirm the Installation

Exchange-Server-installation-confirmation-coexis

Now we have New Exchange Server EX02-2019 in Exchange Admin Center as a co-exist Exchange

 

Configuring New Exchange 2019 as Co-Exist Exchange Environment

As its, a fresh server and virtual directories are pointing to the same server name

Therefore, we have to configure the virtual directories, Outlook Anywhere and Autodiscover scope first

  1. Configure Outlook Anywhere

 configuring outlook anywhere

2. Now configure all virtual directories (except Powershell virtual directory) as the old Exchange2016

As we are using Namespace as mail.techijack.live, (you have to set your namespace)

So, let’s run the following cmdlet to quickly set all the virtual directories in one go, except PowerShell VD

$Server_name = “EX02-2019”

$FQDN = “mail.techijack.live”

Get-OWAVirtualDirectory -Server $Server_name | Set-OWAVirtualDirectory -InternalURL “https://$($FQDN)/owa” -ExternalURL “https://$($FQDN)/owa”

Get-ECPVirtualDirectory -Server $Server_name | Set-ECPVirtualDirectory -InternalURL “https://$($FQDN)/ecp” -ExternalURL “https://$($FQDN)/ecp”

Get-OABVirtualDirectory -Server $Server_name | Set-OABVirtualDirectory -InternalURL “https://$($FQDN)/oab” -ExternalURL “https://$($FQDN)/oab”

Get-ActiveSyncVirtualDirectory -Server $Server_name | Set-ActiveSyncVirtualDirectory -InternalURL “https://$($FQDN)/Microsoft-Server-ActiveSync” -ExternalURL “https://$($FQDN)/Microsoft-Server-ActiveSync”

Get-WebServicesVirtualDirectory -Server $Server_name | Set-WebServicesVirtualDirectory -InternalURL “https://$($FQDN)/EWS/Exchange.asmx” -ExternalURL “https://$($FQDN)/EWS/Exchange.asmx”

Get-MapiVirtualDirectory -Server $Server_name | Set-MapiVirtualDirectory -InternalURL “https://$($FQDN)/mapi” -ExternalURL https://$($FQDN)/mapi

Set-ClientAccessService -Identity EX02-2019 -AutodiscoverServiceInternalURI https://mail.techijack.live/Autodiscover/Autodiscover.xml

3. Furthermore, we also have to set the Autodiscover scope to mail.techijack.live (your namespace)

Set-ClientAcessService -Identity EX02-2019 -AutodiscoverServiceInternalURI https://mail.techijack.live/Autodiscover/Autodiscover.xml

Configuring Autodiscover scope in exchange 2019

 

Installing SSL Certificate To Exchange Server 2019

Now export the existing SSL Certificate from Exchange 2016 and import it to the new Exchange Server 2019

Once you import the SSL Certificate, assign it to the IMAP, IIS, and SMTP service

Importing ssl certificate to exchange server 2019

We have set our SSL certificate on Exchange 2019

In our case, we are using let’s encrypt free SSL, so we install the pfx on our new Exchange 2019

Though it’s free it works for lab environments and small setups

Your case may be different, so you can just export and import the SSL Certificate on your new server

Let’s continue Migrate Exchange 2016 to 2019 in part -2
