currently I have several web apps delivered from an external hoster - there, dehydrated was used to generate ssl certs.
I want to move all those web apps to our internal computer center, where I use Certbot.
Obviously, I do not want a lot of downtime.
What kind of strategy do you propose?
Do I have to copy over the certs?
Can Certbot be forced to directly ask the relevant name server instead of a generic one, so it does not take a lot of time for the updated DNS data to be propagated?
Thank you for any tipps.
