Not sure if I am the right person for a technical advice but the 'broken' SEO Greg is talking about is almost certainly missing 301 redirects. If your old URLs (like your custom blog posts or specific landing pages) weren't mapped to the new Adobe URLs, Google thinks the content is dead.
The only real solution is to force their hand:
Get your marketing team to pull a list of your top-performing URLs from the old site (check your historical Search Console data).
Map those directly to the closest corresponding page on the new site in a simple spreadsheet.
Open a high-priority ticket with the Porsche website support desk and demand they upload that specific redirect map into the Adobe URL Mapping tool.
Corporate won't do the manual work for you, but if you hand them the map, they have to fix it. Until then, you're basically paying for a digital billboard that nobody can find the exit for."
