For PPPoE with existing IPv4, go dual stack.

Core, peering, work outwards towards end users.

There is a lot written and presented about IPv6 deployment. People have 
been doing this in volume since around 2010, and if you search for IPv6 
deployment experience you'll find lots of presentations.

Some I found that seem relevant:

https://www.nanog.org/meetings/nanog51/presentations/Monday/aronson-pierantozzi-level3-ipv6.pdf
https://www.ietf.org/proceedings/54/slides/plenary-15.pdf
https://www.apnic.net/community/ipv6-program/ipv6-stories/
https://www.ipv6council.be/experiences-de-deploiements-ipv6/

If you prefer video form, there are lots of presentations from 
conferences, available on youtube as well.
