Hi Chris,
first of all, you seem to be talking about Knot DNS, so it's proper to
switch to correct mailing list, instead of Knot Resolver's one.
I assume you have read all the single-version migration guides below
https://www.knot-dns.cz/docs/3.0/singlehtml/index.html#upgrade-2-6-x-to-2-7-x
. It's clear that when migrating over multiple versions, you need to
take care about all the notes at once.
What databases exactly are you talking about? Knot DNS uses multiple
databases for different purposes, e.g. journal or KASP DB. The good news
is, their format does not change much, and when it does, it's usually
backwards-compatible, with some exceptions.
I would strongly recommend that you clone your environment, perform the
migration in some "playground" setup first, and observe if everything
went well; all before migration your production setup ;) Should you
encounter any issues, please contact us on our mailing-list.
Anyway, you might consider a multi-step migration, so that you would
migrate by just one (major) version at once, like this: 2.6.5 -> 2.7.8
-> 2.8.5 -> 2.9.9 -> 3.0.5.
Thanks!
Libor

Subject: [knot-resolver-users] Any "gothcas" going from 2.65 to 3.04 I should

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.
