What?

Maybe I just don't understand the context or conditions here, but
...

Isn't it possible to stand up a new signing and publishing setup
with new ZSKs and new KSKs, and have both the old DS record
pointing to the old setup's KSK and a new DS record pointing to
the KSK of the new setup registered in the parent zone, and then
change the actual delegation (NS records), while still retaining
both the two DS records for a while until the data from the old
setup has timed out?

There is then no need to share the secret part of the KSKs or the
ZSKs between the old and the new providers, or to include both
the new and the old ZSKs in the zone.

Regards,
