Why not ? If you used 'PYTHON=python2 ./configure' before, then you
should just use './configure' this time. If, as it seems, you compiled
Samba over an existing Samba directory, then you can get 'left overs',
which you seem to have.

As this is a DC, I would just join an additional DC to the domain
(using the latest Samba) and then demote the old DC.

Depends, if you just ran './configure', then delete /usr/local/samba
(after backing it up), if you used a different PREFIX, then delete

As I said above, just join a new DC instead.

I will have a look at the wiki and try and make it clearer.
