Big-IP VE LTM V14 to V16 then to V17 upgrade licensing question

So apparently, the original licenses were for v13.  I did a grep Exclusive_version /config/bigip.license and received:

Exclusive_version :           11.6.*
Exclusive_version :           12.*.*
Exclusive_version :           13.*.*
Exclusive_version :           14.*.*
Exclusive_version :           15.*.*
Exclusive_version :           16.*.*
Exclusive_version :           5.*.*
Exclusive_version :           6.*.*
Exclusive_version :           7.*.*
Exclusive_version :           8..

I was able to upgrade to 16 but when I went to 17 it said license not valid.  Does this mean I need to purchase new licenses?
