we are in process of migrating from sbs 2011 to server 2019.
we have already installed server 2019 and had joined the domain, now going through the migration guide we have removed the sbs client agent from the server, does the server 2019 required to disjoin from the domain and rejoin or we can proceed with the guide steps normal to install the DNS and other components?
we also have a secondary domain server running on server 2016 in our network environment.
Now that the new 2019 is joined to the domain install ADDS as described in the kit and promote it to a domain controller. If you have problems send me an email.
