Hi @bre122,
I would definitely suggest that you reach out to the Canvas team at PSU about this. I have been in some discussiuon groups around course archiving with them, but I don't know all of the exact rules/proceses/procedures they put in place and whether the archiving applies to all of their Canvas sites or perhaps there are certain subaccounts that are exempt from the process that your course could be moved in to (if it qualifies). All of the archiving things are basically institituion policy and nothing Canvas itself does, so the local team as PSU will be the authority on this one.
Hope this helps!
