Updating Acrobat Standard 2017 to Pro

[NPHA]

Good morning, I have two questions today:

What are the differences between Acrobat Standard 2017 and the Pro version?

If I want to upgrade from Standard to Pro what is the cost and how do I go about upgrading?

Comparison (it's for the DC version, but at the moment that's pretty much the same as the 2017 version): Plans and pricing | Adobe Acrobat DC

To buy an upgrade go to the Adobe Products Page: https://www.adobe.com/products/catalog/software.html

Click on the Buy button next to Acrobat Pro 2017, and then change the "I want to buy" option to "Upgrade", and then select your current version under "I already own", and proceed from there.
