asked on Migrating from Windows Server 2008 R2 to Windows Server 2019 Essentials
I'm seeking step-by-step advice on migrating an on-prem Windows Server 2008 R2 server to a new on-prem server running Windows Server 2019 Essentials. The client has fewer than ten users, so Essentials seems the appropriate version for them. Their 2008 server is a Domain Controller. It's their only server.
I'm asking for the list of steps that move the old server files and configuration, including the Active Directory configuration, to the new serve. Thanks, Experts!

arnold, do I need to worry about going through 2012 and 2016 if I’m moving to new hardware? (I thought I only had to be concerned about the intermediate versions if I was planning to upgrade the OS in place on the old server.)
Going through intermediate steps deal with two separate tracks
1) server upgrade path which you analyzed correctly,
2) deals with maintaing and transferring existing AD versions. 2008/r2 to 2012/2016 no direct path to 2019, then the 2019 can be joined when the AD forest/domain level is at least 2012 and sysvol replication relies on dfsr.
The difficulty since you chose essentials, you can not setup a domain trust to start a new domain on the 2019 ....

arnold, can you elaborate on the steps comprising these two separate tracks?
You are not going in place upgrade because you are going to different version.
Make sure your current sysvol is setup for dfsr based.
Using the tools on the 2019 DVD, you need to run the adprep to update domain, schema, GPO
Look at the following, it seems it might be possible to add a Windows server 2019 as a DC .

Which current clients do you have?

I'm sorry, but I don't understand your question.

arnold, in case you were referring to the client computers, those are Windows 10, with perhaps one still on Windows 7.

Make sure the existing DC is set for DFSR based replication and not FRS which is not supported by the server 2019

How are currently the computer(clients) access the shared folders, server based on domain based shares?
Does the existing fileserver (2008) includes the DFS /dfsr features enabled?

Before you do anything, I would defiantly visualize that box so if things go bad you can still have a DC in your back pocket. You don't need to image the data, just the sys drive.
If you virtualize the DC for backup purposes nothing stops you from making a duplicate, offline copy of it and test the upgrade process.
The asker is not going through an in-place upgrade.

I’m pretty sure Win2019 Essentials can’t join another domain. Given that, what are my options for transferring AD information? Also, having never done a server migration, I ask, what’s the concern about replicating sysvol?

Thanks, all. I think I'll be migrating by hand.
Look at dfsmig whether your sysvol uses FRS or dfsr.
You would need to use intermediate server 2012/2016 before you can get to server 2019.
