After reviewing the relevant thread it looks like diagnosing the issue
was not possible due to lack of logs.

First make sure you can list users, groups, sudo rules, hbac rules on
your existing IPA cluster.
Then setup a new IPA instance on a clean host, add replica(s) and then
create all the necessary objects like users, groups, sudo rules,
HBAC... and then you will have to run ipa-client-install (e.g enroll
again) on all the existing clients.
Migrating the configuration in one go is not yet possible.
Please make sure logs are properly written, use backups and add
monitoring for your service certificates.
