My plan was to do this and then transfer FSMO roles and be done but I'm getting an error (WERR_DS_DRA_MISSING_PARENT) trying to join the domain with the new version. Based on another mailing list posting by Andrew, it looks like this happens with very old versions of Samba.

You could try compiling 4.3.0 yourself, then try and join it as a new 
DC, if that works, transfer the FSMO roles to the new DC and demote the 
old one. I would then try 4.5.0 , once at 4.5.0 you could then try a 
bigger jump, say to 4.13.0.

This will all take time and work, depending on the size of your AD 
domain, it might just be easier to start again.

Once you do have a your domain working with a supported version of Samba 
(You appear to be approx 16 major versions adrift, the latest is 
4.17.4), I would suggest you try and keep up to date.
