Since KSK roll is rare and needs manual work anyway, I think we can 
fully re-sync instances (copy kasp.db etc.) then and continue.

Currently we have two replicated registry back-end systems,
to which we plan directly attach signing servers with HSM cards 
(utimaco) (with hundreds of keys pregenerated and cloned).
Second signing server should be ready to sign in case of registry system 
switch over, however we don't need to reuse signatures (full zone resign 
is fine).
I would prefer to avoid replicating opendnssec servers to keep it more 
simple and have identical zone-in-zone-out sign boxes, so that I can 
just replace one with other in case of hw failure etc.

Thanks all for information.
