My goal is to migrate from freeipa v3 to v4. Both versions are a cluster of two nodes.

v3 is centos 6 and v4 is centos 7.

I want to migrate the dns entries from the old cluster to the new one. Both have the same dns zone(s) and after all dns entries are on both clusters I will migrate all hosts to the new cluster. Also the users will be created manually. Goal is to have a fresh freeipa environment.

Which commands do I need to know or use to achieve that? Also an export and import function will do the trick.

This is all documented in the official documentation in the "MIGRATING IDENTITY MANAGEMENT FROM RED HAT ENTERPRISE LINUX 6 TO VERSION 7" section: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/linux_domain_identity_authentication_and_policy_guide/migrate-6-to-7

The key is not to start from scratch but rather add CentOS 7 replicas to CentOS 6 deployment, move services over to CentOS 7 replicas and then decommission CentOS 6 machines. This is, in general, much easier and more reliable to do than to start from scratch by importing older data.
