Migrating from Exchange 2010 to Exchange 2016 Part-2

In the first part,  i have given basic process to migration any of the legacy to latest Exchange version, as you know we are working with process orientated organization so we have to have follow the the process.

In this part i will focus on planning & pre-requisite for introduce the Exchange 2016 into existing Exchange 2010  environment.

First of all we have to understand the major changes on the Architectural of Exchange 2016, in Exchange we do have separate servers roles : Mailboxe, Client Access, HUB Transport & Unified Messaging. In Exchange 2016 Microsoft introduced only one server role, which contains all components.

We have to follow some best practices before deployment such as :

Exchange Server Sizing

As we know in Exchange 2016 we do have only one Server roles which is taking care of all Exchange components so it means hardware sizing is the most critical part of deployment.

You can use the Exchange 2016 server requirement calculator  which will give you a clear way to implements the Exchange server in existing environment.

I'm going to use VMWare environment in this series so i will follow the best practice to implements Exchange Server into VMWare.

As i mentioned in previous part assessment, based on the assessments result you have to decide or input the data into calculator and find out the hardware.

Updating Existing Environment

Before introduce the Exchange 2016 into Existing environment you have to have update the Exchange 2010 with require Service Pack 3 with Update Roll up 11.

You can download from here 

Directory Service Requirements:

In Exchange 2016 Microsoft recommended first time minimum support Forest Functional Level and Domain Functional Level is now Windows 2008 or above. So make sure your environment is ready for this.

Updating Outlook Clients:

As you already know Exchange 2016 support outlook 2010 and above on Windows and on the Mac Outlook 2011 and higher.

All version of Outlook 2016 and Outlook 2013 are supported, Outlook 2010 is supported with the latest updates ( KB2965295).

Here you can check the support Outlook version.

Naming Services:

Before implements you have to decide the names used by the clients to access the Exchange. In Co-existence  with Exchange 2010, 2013 and Exchange 2016 allows sharing of the same  HTTPS names for autodiscover, OWA, Activesync and other services, which will make your transition very easy, so before moving forward you have to finalize the names.

Preparing Hardware (VM) for Exchange 2016:

In my LAB environment i do have some hardware limitation so i'm using minimum requirements which is not going to follow into production environment.

I have already assigned 6 core CPU and 16 GB RAM.

Get the disk details which i added in to VM

Now bring the online which is in offline mode
Get the Partition details
Assign the drive latter

Now format disk with new file system called  "ReFS"

Finally get the details

In this part i have cover basic requirement of the environment before installing the Exchange server in existing environment, which is very critical.

In Next part i will start introduce Exchange 2016 server in existing Exchange 2010 environment.

Hope this part also help you to plan your environment to Exchange 2016.

Thanks you.
