    Hi,

    Yes, it is possible.

    You could deploy a hybrid environment, which will include the features introduced in the official document below

    Exchange Server hybrid deployments

    Then you can choose the users you want to move to cloud, and other users still locate on-premise

    Detailed information here: Move mailboxes between on-premises and Exchange Online organizations in hybrid deployments

    For the guide to help you deploy your hybrid environment, using this: Microsoft 365 and Office 365 mail migration advisor (login your Microsoft 365 or Office 365 account with Global administrator permissions)
