IPv6 Migration is generally not aided by CGNAT.

In general, the economics today still work out to make purchasing or leasing addresses more favorable than CGNAT.

It’s a bit dated by now, but still very relevant, see Lee Howard’s excellent research presented at the 2012 Rocky
mountain v6 task force meeting:

We'd probably be looking at a solution to support 5k to 15k customers and bandwidth up to around 30-40 gig as a starting point. A solution that is as transparent to user experience as possible is a priority.
