How to Migrate Exchange 2010 to 2016

Hello guys, today we are going to discuss about how to migrate Exchange 2010 to 2016. It’s not a very lengthy process to achieve but it is the process which should be performed carefully.
I am considering that Active Directory and Exchange Server 2010 is already installed and configured very well and it is running right now in the user machine. I am also considering that Exchange 2016 is already installed in the organization, which is currently running Exchange 2010.

After making sure that all the conditions, which I have mentioned in above paragraph, are true, we will proceed to the Migration Process from Exchange 2010 to 2016.
We have to move Arbitration Mailboxes from Exchange Server 2010 to 2016. Arbitration mailboxes are those mailboxes which are used to store audit logs, eDiscovery searches metadata & unified messaging data, custom greetings and dial plans. If we don’t move arbitration mailboxes then CMDLET of Exchange 2016 won’t be logged in and its eDiscovery searches won’t start.
So, let’s proceed to move arbitration Mailboxes from Exchange 2010 to 2016. We will discuss it in steps with pictorial representation.
  1. Firstly run Exchange Admin Center (EAC) and login Using Administrator User Account Credentials.
  2. After Logging in into EAC click on Recipients tab present in left division. Then click on Migration option present at center of screen at right side of shared. You can see Fig 1 for reference.

  3. Now click on Add (+) sign at the left side under Click to view the status. See Fig 2 for reference.

We discussed about how to migrate Exchange 2010 to 2016. As we saw it’s not a very difficult task to perform but it is risky to perform. Risks include data loss, data corruption etc. If your mailbox is already corrupted then I will suggest you to first repair corrupt Exchange 2010 mailbox then proceed for migration of Exchange Server mailboxes. If there is anything else you want to ask or have any confusion about migration then you can write in comment section.
