Yes, the current keys are alg 7 2048 bit. Is there a document on the various
options here? I am plowing through the "BIND 9 Administrator Reference Manual,
Release BIND 9.16.5 (Stable Release)" but it is slow going right now and
"dnssec-policy" does not appear in the pdf in a searchable form, which makes
things even more fun).
(This domain has a RRSIG range of 20210122220953 - 20210221230953)
I am guessing as soon as I add that DNSSEC-policy I also need to change each
domain record from "auto-dnssec maintain;" to "dnssec-policy default;" or do I
do that after the .state files have been created? (That doesn't sound right,
but best to check).

So once all the domains have a .state file associated with them in the key
directory I can change the dnssec-policy to the sample I had before and it will
just migrate from the alg 7 keys above to alg ECDSAP256SHA256 (or I can just
say alg 13 instead).
#v+
dnssec-policy alg13-ksk-unlimited-zsk-60day {
keys {
ksk key-directory lifetime unlimited algorithm 13;
zsk key-directory lifetime P60D algorithm 13;
};
};
#v-
That seems very straightforward, there must be a catch somewhere.
