I got it thanks. This was the link it sent me to which really didn't help( https://docs.microsoft.com/en-us/sccm/core/plan-design/changes/deprecated/removed-and-deprecated). After I looked at the log it was pretty clear, i had a Distribution Point that was still running 2008R2 and it was causing the issue. I upgraded the server last night and now the prereq passes. I will do the upgrade tonight. Thanks
