[knot-resolver-users] Any "gothcas" going from 2.65 to 3.04 I should know about?

Hi. Moving a couple of our servers to new hardware, and taking that opportunity to upgrade some of the services at the same time. The main one being knot. Moving from a 2.65 context to 3.04. I've read the upgrade doc, and while there isn't a 2.65 --> 3.04. It appears for our environment that the changed/removed stanzas won't have much of an impact *except* as they relate to the database. That is; it appears that it isn't going to be a smooth transition, as they appear to be incompatible. Is that right? Do I need to rewrite all the keys && serials, and start from scratch? If so, as we have a huge number of domains, this will be an enormous task. Is this avoidable? Thank you for any and all insight into this transition. --Chris
