all the best

Hi,
If you are not familiar with O365 PS I suggest you to use Office365 portal to move the users from onprem to O365.
Create migration end point

Move users

You can select multiple users in a batch.

Thanks

Hi guys, and thank you for your answers.
I may have worded my question wrong, english is not my native language.

I do not want to use the portal, I want to learn how to do it in Powershell.
I´m already connected to Office365 with powershell and I can remotely move individual mailboxes from my onprem to office365 by using the -Identity parameter.
What I need to know is: Can I remotely use something like Get-Mailbox -Database <Name of Onprem database> and pipe it to -NewRemoteRequest ?
Or do I need to connect to the onprem exchange server in a separte powershell window  and do it from there ?
Thanks for your patience.

Siggi

Hi Siggi,
You can install Msoidclient in any PC in your network.

If you want to move in bulk export the email address from the database to CSV and move to O365.

Hi.
I think I have erverything I need innstalled on my computer  ( I have the MSOidclient installed ).
I´m just checking if it is possible to move ALL the mailboxes from an Onprem database ( Get-Mailbox -Database "OnPremdatabaseName" and pipe it to a Remote-Move command from my already open remote Powershell connection window, no CSV file, just get all the mailboxes in an  Onprem database and move them to the Office365 cloud.
Does anyone hava a one line command for that if possible at all ?

Maybe it´s just not possible, I only wanted to know :-)

Siggi

Thank you, that was what I wanted to get me on my way.
