In your instance, as you now have a fairly recent version of Samba on 
your second DC, you will already have all the benefits of the latest 
index and database improvements.

I would transfer the FSMO roles to the second DC, then demote DC1, 
remove the existing Samba packages and clean up anything 'Samba' left. 
Install the new Samba packages (this should recreate the Samba 
directories) and then join to the domain as a DC, as you did for DC2.

The other way to do this would be to transfer the FSMO roles to the 
second DC, then demote DC1 and then re-install the OS, this would also 
allow you to upgrade the distro.
