User reported issue running ipa-server-upgrade. An indexing task was hanging.
Thierry diagnosed it this way:
So indexing is hanging because SC cache_init is running, the SC cache_init is hanging because SSSD is not started, SSSD is not started possibly because indexing prevents to get read access to the backend ("Backend is offline" TBC).

If schema compat is enabled the state should be saved similar to what is being done for nsslapd-port, etc., disabled and then restored when the upgrade is finished.
