Hey Rya,
You will need SASU contract support at a minimum
Cisco Software Application Support plus Upgrades (SASU)
Provides all of the same features as SAS plus major software application upgrades. Upgrades provide a richer feature set and improved performance and efficiency.

You can send an email to determine your access rights to PUT (see below)
From the PUT Q&A
9.) What is required to obtain access to the Product Upgrade Tool?
Only registered users with a Cisco.com account and contract entitlement can use this tool. If you are unable to access the Product Upgrade Tool, send an e-mail to cs-support@cisco.com with the keyword PUT-ACCESS in the subject line of the e-mail. Be sure to include your CCO userID and applicable contract number.
