The IETF BCP is to deploy Dual Stack, thus both IPv4 and IPv6 at the
same time.

When that is not possible, as you ran out of IPv4 addresses, you should
look at Dual Stack Lite (DS Lite) eg as supplied by ISC's AFTR and other
such implementations.

Depending on your business model you can of course also stick everybody
behind a huge NAT or require them to use HTTP proxies to get to the
Internet as most people define it...

Do note that if you are asking any of these questions today you are
years late in reading up and you missed your chance to be prepared for
this in all kinds of ways.
