It isn't supported to introduce 2019 domain controllers to a 2003 DFL domain.
Also FRS needs to be migrated to DFSR before adding 2019 domain controllers.
So you'll need to do this two-step, first by migrating to 2012 R2 or 2016, removing the 2003 DCs in order to raise DFL to minimum or 2008 R2, then do the FRS-->DFSR migration, then bring in the first 2019 domain controller.
To the domain controller migration general steps below;
I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting. Then stand up the new guest, patch it fully, license it (you can use evaluations for the interim step), join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to verify health, when all is good you can decommission / demote old one, move on to next one.

The info on the new Storage Migration Service tool states that it can migrate from Server 2003 directly to Server 2019. Is that info incorrect? Ned made it look so simple in his Ignite presentation. (Though he was using a server far newer than 2003!) So far I'm unable to find any detailed documentation on how to do this with SMS. Any good pointers?
The SMS info is here: https://docs.microsoft.com/en-us/windows-server/storage/storage-migration-service/overview The Requirements for Source Servers lists Server 2003 and Server 2003 R2. It would be great to find a step-by-step on how to prepare the Server 2003 system to interact with the SMS tools.

Since a new topic and user I'd start a new thread to maintain forums clarity.

Actually, no its not. This thread was about domain migration. But even so each user's issues are unique and should be asked in a separate thread where the originator can control the thread. Plus by separating the threads user's searching for answers will get more meaningful results.

Hi Dave, I also face the similar scenario: migrating from 2003 to 2019. I find your another reply here:
However, when I use dcdiag in my 2003 server, there is only 1 error:
Starting test: frsevent
There are warning or error events within the last 24 hours after the
SYSVOL has been shared. Failing SYSVOL replication problems may cause
Group Policy problems.
......................... (dc name) failed test frsevent
Does it matter? Will it stop my from migrating?
Also, if I have only 1 DC, should I still use repadmin to check the replication? Or I will only use it after I have setup 2012?
Thank you very much
