Description of problem:
Section "3.4.2. Installing Aodh" of https://access.redhat.com/documentation/en/red-hat-openstack-platform/9/single/upgrading-red-hat-openstack-platform
does not include instructions to include "--force-postconfig" option required to create new endpoints for Aodh. This step includes calling 'e major-upgrade-aodh.yaml.
There is no mention of "--force-postconfig" anywhere in the documentation.
Without this option endpoints are not created, Aodh will not start. Deploy will fail.
Version-Release number of selected component (if applicable):
Follow OSP 8 to 9 Upgrade Guide
Steps to Reproduce:
1. Attempt to upgrade OSP 8 to OSP 9 following official doc
2. Include major-upgrade-aodh.yaml
3. Install fails
Upgrade fails during deployment
Deployment including major-upgrade-aodh.yaml completes without issue
