When swicthing versions, it is very important to read the upgrade
guide (and other docs) first. Also read and understand
https://blog.powerdns.com/2016/01/18/open-source-support-out-in-the-open/

Only if you think for yourself first and give complete information to
the list we can maybe help you. At the moment, your messages only
cause noise on the list.
