    Hi @Yasrosa ,

    1- How can we migrate the Domaincontroller and the Exchange Mailboxes? what is the best way for that?

    For DC migration, the recommended way to upgrade a domain is to promote new servers to DCs that run a newer version of Windows Server and demote the older DCs as needed. Prerequisites and steps you can refer to:Upgrade domain controllers to a newer version of Windows Server | Microsoft Learn

    For Exchange migration, you can setup the exchange server on the new Windows Sever, migrate things over and then decommission the old one. More steps you can refer to: Performing a Like for Like Exchange Server Migration Please Note: Since the web site is not hosted by Microsoft, the link may change without notice.

    2- After the Migration, should we deinstallieren the Roles on the DC & Exchange?

    As far as I know, Roles will be transferred during the configuration phase of the new server. After the migration is complete you can remove the older server.

    You can perform a cross-forest move request to migrate your mailboxes from the legacy Exchange 2019 to the new server: Prepare mailboxes for cross-forest move requests. At the same time, back up configurations (except the default ones) of your legacy server(e.g. Connectors, Permission, Transport rule etc.) and apply them to the new server according to your requirements.

    Hello, There is a quite explanative article in the MS Techcommunity that covers the DC migration: https://techcommunity.microsoft.com/t5/itops-talk-blog/how-to-migrate-active-directory-from-windows-server-2012-r2-to/ba-p/329861 For Exchange, since all the infrastructure will remain on the same On-Premises, you can create a new Exchange Server on the new host, then migrate mailboxes: https://learn.microsoft.com/en-us/exchange/architecture/mailbox-servers/manage-mailbox-moves?view=exchserver-2019 Then to decomission the old Exchange server, you can follow this article: https://techcommunity.microsoft.com/t5/exchange-team-blog/decommissioning-exchange-server-2013/ba-p/3613793 --If the reply is helpful, please Upvote and Accept as answer--
