Hi,

never mind, but I belief that I found an answer to one of my questions in the meantime.

https://labs.ripe.net/Members/anandb/dnssec-algorithm-roll-over
https://medium.com/nlnetlabs/algorithm-rollover-in-opendnssec-1-3-bf1dfa480aa7

Both articles suggest that one should change the algorithm on both keys during a simultaneously rollover operation with additional precautions.

(Because I am using OpenDNSSEC v2 I will take the second article as a guideline.)

With kind regards,
