Hello,
we migrated two Zimbra servers from Centos 6 and 7 to RHEL 8. We followed https://wiki.zimbra.com/wiki/ZCS_to_ZCS_rsync_Migration. The migration was successful, all services are working. But you can't start cbpolicyd. One server had cbpolicyd before migration, the service does not start after migration. On the second server a new installation of cbpolicyd - service will not start. cbpolicyd.log is deaf. The problem must be related to the migration itself, but what to look for when there is no mention of an error in the log?
On the second server we configured CBpolicyD according to https://imanudin.net/2014/09/08/how-to- ... imbra-8-5/ we also tried https://wiki.zimbra.com/ wiki / CBPolicyD_Management.
Zimbra version on both servers is 8.8.15.
