[Freeipa-users] Upgrading from 3.0.0 CentOS6 to 4.2.3 CentOS7

[Ash Alam]

I wanted to follow up on this as i finally gotten around to doing the
upgrade. I an running into this error. I also found a bugzilla ticket. Do
you have to do some type of schema upgrade like you do with active
directory?

https://bugzilla.redhat.com/show_bug.cgi?id=1235766

    STDERR: ipa         : CRITICAL The master CA directory server does not
have necessary schema. Please copy the following script to all CA masters
and run it on them: /usr/share/ipa/copy-schema-to-ca.py

    If you are certain that this is a false positive, use
--skip-schema-check.

    ipa.ipapython.install.cli.install_tool(Replica): ERROR    IPA schema
missing on master CA directory server



Thank You
