Yes and no. I found the reason OMSA upgrades failed is the version of OMSA SupportAssist was trying to install 9.1 is not compatible with Server 2008r2. It would actually corrupt the OMSA installation and require a manual uninstall/reinstall of 8.4 to be functional again. Not sure why Dell SupportAssist is pushing a version of OMSA that breaks itself because it is not compatible.
I cannot get SA to upgrade OMSA. I pick a server that says New version of OMSA available. Then tell it to Install/Upgrade OMSA.  It switches to Installing OMSA for a minute then back to New version of OMSA available How do I complete the upgrade successfully.
[CLOSED] OMSA never upgrades through SupportAssist
