DNSSEC and upgrading/restoring

[David Newman]

Are there any recommended practices/config changes needed when upgrading
or restoring a bind 9.9.4 server using DNSSEC inline signing and auto
maintain?

Asking specifically about upgrading a server running on NanoBSD, but
this question is really about upgrading or restoring any DNSSEC server
with inline signing and auto maintain enabled.

Is this as easy as copying everything from /var/named to the NanoBSD
build machine and going from there? Or is something else required?

Thanks!
