I am upgrading Exchange 2016 CU3 to Exchange 2016 CU9. Updates for Exchange Servers are…
New-MigrationBatch or New-MoveRequest in Exchange
There are two ways when it comes to moving mailboxes between on-premises and Exchange Online organizations. One way is with New-MigrationBatch, introduced since Exchange 2013. The other way is with New-MoveRequest. In this article, we will compare both features.
Information
You read a lot about moving a mailbox, and you like to know which options are available. Think about when you have to prepare a massive mailbox migration to Office 365, or from Exchange Server 2010 to Exchange Server 2016.
There are two options available to move mailboxes, that’s the New-MigrationBatch and the New-MoveRequest feature.
If you want to look at the primary purpose of both features, there is no difference. That’s because both of them will move the mailbox from the source mailbox database to the target mailbox database. But what’s the difference then?
New-MigrationBatch vs. New-MoveRequest
| Description | New-MigrationBatch | New-MoveRequest |
|---|---|---|
| Move mailbox between on-premises mailbox databases | ✓ | ✓ |
| Move mailbox to and from Exchange Online (Office 365) | ✓ | ✓ |
| Immediately starts the mailbox transfer | ☓ | ✓ |
| Migration status report | ✓ | ☓ |
| Exchange 2010 support | ☓ | ✓ |
| Exchange 2013/2016/2019/Exchange Online support | ✓ | ✓ |
| Move one mailbox | ✓ | ✓ |
| Move many mailboxes | ✓ | ✓ |
| Move mailboxes with a CSV file | ✓ | ✓ |
| Makes use of Migration mailbox (arbitration mailbox) | ✓ | ☓ |
| Available in Exchange Admin Center | ✓ | ☓ |
| Available in Exchange Management Shell | ✓ | ✓ |
Which one to choose?
You have a migration planned, and you have to move thousands of mailboxes. Maybe you like to move a single mailbox or many mailboxes. Which of these two options should you choose:
- New-MigrationBatch
- New-MoveRequest
I do recommend moving mailboxes with the New-MoveRequest as it’s faster. There is no Migration mailbox involved in the process. If the company asks for a detailed report after the mailboxes finished moving, go for option 1.
If you want to move the mailboxes with a wizard (GUI), you must choose for Exchange Admin Center. In the back-end, it will make use of the New-MigrationBatch feature. If you want to move mailboxes with the New-MoveRequest feature, you have to use Exchange Management Shell.

Hi
For some reason I ended up to your page “New-MigrationBatch or New-MoveRequest in Exchange”. I wasn’t looking for this information but in the past it’s have been a topic that I have been interested in so I ended up reading your blog page.
I just wanted to ask “why the migration batch is faster than new-moverequest?”. During the years as an Exchange admin I have felt that it’s the other way round and migration batch starts more easily to hang in starting the batch or in finishing it.
And if you are looking at what happens when a new migration batch is created it creates moverequests for the transfer. So basically it’s a one layer above moverequests. So there is more possibilities for errors and something not functioning. Also for this reason I feel like that it can’t be faster because it’s still based on moverequests. Sure the GUI might say that transfer has started even if it’s not true… what comes to finishing of the batch it might take sometimes hours to update the status on migration batch (while moverequests were finished already).
I really don’t know how migration batches technically works (in under the hood). My comments are based on observation and mailbox transfers in different environments. That’s why I have interest in this matter.
Best regards,
Petteri
Hi Petteri,
Your information and observation are correct. That’s how it works.
New-MoveRequest is faster than New-MigrationBatch.
I have written in the article, “I do recommend moving mailboxes with the New-MoveRequest as it’s faster. There is no Migration mailbox involved in the process.”
But, I do see that what went wrong. The checkmark for “Immediately starts the mailbox transfer” is placed in the wrong column in the table. I updated it right now.
Thanks!
