Upgrade SmartProxy to katello 3.5 from katello 3.4 fail with puppet version error

Hi all,

I have the issue at this time i can’t upgrade the smartproxy because this smartproxy use old puppet 3.8 but the new version of katello apparently needs version 4 but i don’t see any kind of methodology to do it in the katello page. in the new version of katello 3.5
