Blaze Advisor upgrade(7.4)

I am using blaze advisor 7.4. I went through the pdf docs but did't get any idea how to upgrade my project with latest version i.e blaze advisor 7.4

In my project there are a folder where adv, dbcp,flow jcp, rb files are there Also in lib folder there are Advisor.jar,AdvisorDev.jar,AdvisorSvr.jar etc.I have been asked to upgrade that project with latest version of blaze advisor(7.4)

I am new to this

So please tell me all the steps to port in the existing code in new version of blaze advisor(7.4)
