Moving users from on-premise AD to Azure AD

Hi,

Currently we have our on-premise AD syncing to our Azure AD. We recently began to create new users just on Azure AD. We would like to move our current users from the on-premise AD to our Azure AD. It's about 7,600 users between two OUs. We are also planning to join the computers these accounts would use to the Azure AD.

I thought that breaking the sync would just keep the users in Azure AD, but it tried to delete them. I can't find a tool online that would just migrate the AD accounts to Azure AD. Would I have to manually recreate all the users in Azure AD?

Thank you,
Matt

    Hi @Matthew Love

    Try turning off directory syncing via PowerShell for all cloud users before disconnecting Azure AD Connect:

    Set-MsolDirSyncEnabled -EnableDirSync $false

    Note:

    If you use this command, you must wait 72 hours before you can turn directory synchronization back on.
