Migrate users from on-prem Exchange server to Office 365

Moving users one at a time through the EMC was getting super old so I decided to write a script for it to speed it up. Below is the script that I use to migrate a user from the on-prem Exchange 2010 server to Office 365:

A couple of notes on what the script is doing:

 - You will need to edit the lines in the "Declaring the variables" section to fit your environment
 - Pay attention to the help file at the beginning of the script on how to run the script
 - The first thing the script will do is prompt you TWICE for credentials.
       - Once for Exchange on-prem server (LDAP)
       - Second for Microsoft Online (Office 365)
 - Next it will load all the modules/snapins that you will need during this script
 - Starting the script:

1. First thing that we are going to do is disable Unified Messaging (UM) on the on-prem Exchange server. You can't migrate a user while UM is enabled.
2. License the user in Office 365
3. Set the location for the user to US in Office 365
4. Connect to Microsoft Exchange Online with a new session
5. Create the move request for the user from on-prem to Office 365
6. Sends a conformation email to you once the move has been scheduled.

Here is the script:
(quick note: to run this in bulk, just throw in a FOREACH loop in there before the license part)

  1. Nice article, Thanks for sharing helpful topics related to exchange server to move office 365, it guides stepwise process to Office 365 migrations process. I saw the proficient tool from http://www.lepide.com/exchangemigrator/ that guide about migrate between two Exchange Servers and migration from any Exchange Server to Office 365. It allows to migrate exchange server, cross-forest exchange server and public folder.
