INTRODUCTION
This article describes how to manage the number of concurrent migration batches in Microsoft Exchange Online in Microsoft Office 365.
PROCEDURE
Administrators can set the number of concurrent migration batches for new and existing migration batches by using the Exchange Admin Center (EAC) or Exchange Online PowerShell.
