I upgraded. The upgrade seems to have been successful.
However, the distribution OS of the self-hosted engine did not change.
# cat /etc/system-release
CentOS Linux release 8.3.2011
Do I need to manually change my self-hosted engine distribution to Stream 8?
I saw this URL for the version upgrade procedure.
