Compliance frameworks are generally technology agonistic.
They tell you "have an information boundary for your system",
"manage your user identifiers", etc. Aside from the DoD IA
STIGs (and small handful of NIST areas such as encryption),
you don't find specifications that particular protocols or
technology is required. They don't require major updating
for IPv6 because there's very little IPv4 specific contents
in them already.
That's not to say that moving an application to IPv6 is trivial
from a compliance and security perspective, as you've still got a
pile of mandatory firewall, load-balancing, and IDS infrastructure
that needs to handle IPv6 correctly before you can get started.
In organizations that are planning ahead, this is common security
control infrastructure, and gets done once centrally rather than
each little component.

Look, systems change. Change your database software, and you
get to update the corresponding pieces of the C&A package. Add
IPv6, you have to update the network portions. This shouldn't
be a surprise to anyone, and it certainly doesn't mean "all of
their C&A work will need to be re-done".
