Hello Natxo, During migration, certificates are not touched. This is a bug/deficiency in FreeIPA in RHEL-6.x, it uses the issuing FreeIPA hostname as the CRL/OCSP contact. This should be fully fixed in FreeIPA 3.2 or later, see upstream ticket (and linked design page): https://fedorahosted.org/freeipa/ticket/3547 In the RHEL-7 versions, certificates should be pointing to the joint name "ipa-ca.DOMAIN" pointing to FreeIPA servers with CA. What you can do now is to either keep the "A" record as you already have, or alternatively you can re-issue certificates ("ipa-getcert resubmit") that are pointing to the RHEL-6 machine.
