[ovirt-users] Switching 4.4 hosted-engine from Linux 8 to Stream 8 before upgrading to 4.5

It is my understanding that the 4.4 engine must be on Stream 8 before it can be upgraded to oVirt version 4.5. Is there an easy and reliable way to switch a 4.4 hosted-engine that is still using oVirt's CentOS Linux 8 repositories over to oVirt's CentOS Stream 8 repositories? If yes, how? Also, what would be the rollback/recovery procedure should the switchover fail? In brief, our engine was originally deployed using oVirt Node 4.4.3. At present, the engine is at version 4.4.10.7. Also, all our hosts are running oVirt Node v4.4.10.2 and are using oVirt's CentOS Stream 8 repositories. Any help and guidance is greatly appreciated.
