Anyone have recent experiences upgrading an "old" (pre Feb 12,2017) ticket?

Hi all!

Just wondering if anyone has had any experience upgrading their older tickets at the park now that there has been a price increase? I am curious as to how much it now costs to add a day (going from 7 to 8 days) and also how much to add the water park option?

Here's info from @Dan Murphy in the current Ticket Price increase thread:
$21 to upgrade...
