Ticket Question

[MM_Bound]

I have a couple of old universal tickets that I saved from a trip in 2002 I think. They are no expiry tickets and at that time there was only one park.
My question:
1.Is there a way to upgrade them to a park to park ticket?
Thanks in advance.

Looked closer and also managed out make out some other text that was faded off the back of the ticket, it said 2 Park, so nevermind.
