No, the TLD would be 'fr'. 'TLD' is short for 'Top Level Domain'

No, that would be the dns domain name, the realm is that in uppercase
'NOMRUE205.MONODOMAINE.FR'

> AD domain: nomrue205

No, that would be the Netbios domain name (aka workgroup)

Sorry to be a bit pedantic about this, but it saves problems in the
long term :-)

Again, no, you need to do all this before the classic upgrade, which is
one of the reasons we suggest doing a trial upgrade before doing it for
real, you find all the problems before destroying your production
domain.
