Roadmap for upgrading CloudBees CD/RO
On this page
|Upgrading CloudBees CD/RO versions between 5.x and 8.2 that are using the built-in (default) database is not supported. This means that you must switch to an alternate CloudBees CD/RO-supported database before your upgrade. For instructions, see Switching to an alternate database.|
