Thank you for your response. I powered up the defunct system and confirmed that the keycloak DB was present in the source database, but the engine-backup tool was not backing it up. I was able to recover with the following these steps: 1. start from clean CentOS 9 2. remove a conflicting man page rpm 2. dnf install ovirt-engine, ignore the script error 3. restore the engine database 4. back up the keycloak database with pg_dump, migrate to new engine host, and restore the keycloak database 5. Add entries to the pg_hba for the keycloak database 6. ensure the keycloak user could connect to the keycloak database 7. run engine-setup (no errors) 8. manually add engin.cer to the java keystore We are now running on Version 4.5.4-1.el9 *David Johnson* *Director of Development, Maxis Technology* 844.696.2947 ext 702 (o) | 479.531.3590 (c) <https://www.linkedin.com/in/pojoguy/> <https://maxistechnology.com/wp-content/uploads/vcards/vcard-David_Johnson.vcf> <https://maxistechnology.com/> *Follow us:* <https://www.linkedin.com/company/maxis-tech-inc/>
