[Pdns-users] How to Update from PDNS 4.1.14 to Latest?

[Markus Ehrlicher]

Better not. You are trying to upgrade PDNS Recursor but have installed PDNS Authoritative Server. That will go wrong ;)

Best regards,
Markus

Thanks so much!

That means for PDNS authoritative system, we can update directly through yum with following (on top of existing system):


yum install epel-release &&

dnf install -y 'dnf-command(config-manager)' &&

dnf config-manager --set-enabled PowerTools &&

curl -o /etc/yum.repos.d/powerdns-rec-45.repo https://repo.powerdns.com/repo-files/centos-rec-45.repo &&

yum install pdns-recursor

But we will need to ensure all settings/schema etc that you mentioned are adjusted accordingly so it will still work after that.

Is that correct?

Warmest Regards,
Jackson Yap

I would recommend checking after upgrading :). Usually it makes sense to

1. Install the new version
2. Dump+import or clone the old database
3. Do the schema changes on the clone
4. Test (including running the new pdnsutil)
5. Upgrade the production system

You can upgrade by either upgrading you OS. But even better is grabbing
our packages for your distro from from https://repo.powerdns.com/.

Latest stable auth is 4.4, supported until June next yer (see the EOL
statements[1]. We try to make upgrading as painless as possible, hence
the upgrade guide.

Cheers,
