There are some lessons learned here with NAT-PT
But, i would only use NAT-PT for ... no ... i would never use NAT-PT.
The implementations are really not good.

I have tested 3 versions of DNS64 and 4 versions of NAT64. I am not
sure what i can share about them. My experience has generally been
good. I feel good with taking my selected vendors to production with
this feature. Users in my beta trial have been happy with the results
and performance. You mentioned Cisco. Cisco has stateless support
today of NAT64, but i am not sure the value of that since it is one
for one. I assume they will have stateful support soon.
Juniper has stateful NAT64 today in production code, i have not looked
at this one yet, but it appears promising
If you are talking about servers, not users, most of the commercial
load balancers have NAT64 functions for the IPv6 user to IPv4 legacy
server use case.
