How to add Windows 2019 server to 2008 R2 and migrate DC

I have two Windows Server 2019 servers that I need to add to Server 2008 R2 domain.

It is not possible to add 2019 server to 2008 R2 domain without enabling SMB 1.0 client, and I would like to skip having SMB 1.0 at all on the domain. (For printer scan locations I will use either an isolated VM or internal FTP server.)

The procedure I devised is as follows:

• enable SMB 1.0 client on both servers and add them to domain
• migrate DC roles from old server to new
• remove old server
• remove SMB 1.0 from new server machines
• profit? :-)

Is this procedure OK?

I will have a number of Windows 7, Windows 8 and Windows 10 machines on the network, which should all be able to connect to new domain correctly?

Any tip or info is appreciated, as I am trying not o have to recreate entire domain from scratch.

Thanks!

UPDATE:

Anyway, don't have time to wait for an answer. I compared settings with Server 2016, and see that it has SMB1 enabled by default. So I installed SMB clients on both servers and added them to domain.

I am currently processing updates and such, and will soon proceed to promote one to DC and other one to RDS.

Will post back how it worked.

Interesting quirk - you can't access add to domain using new settings, it is a bug or whatever, but need to go to advanced system settings that are buried deep now.

Solution 1:

The devised procedure worked flawlessly:

1. enable SMB 1.0
2. add to domain
3. install AD DC in roles ad features
4. PowerShell: Move-ADDirectoryServerOperationMasterRole -Identity SERVERNAME -OperationMasterRole SchemaMaster, DomainNamingMaster, PDCEmulator, RIDMaster, InfrastructureMaster

Also to note: IP should be fixed, On both server DNS primary should be new DC, and don't forget to update the DHCP setting to set DC as first DNS server.
