hi there, i am currently in the process of doing something similar..
I hadn't used my PPL since 2012 - got my class 1 medical late last year to ensure I could qualify for a CPL.
I had to update my old PPL to the new Part 61 licence - it was about $25 and was relatively straight forward.
This will allow you to go for a flight review when you are ready. Yep, kinda like riding a bike from what I experienced. things came back to me surprisingly quick.
I have done a couple of revision flights with an instructor recently and feel confident of going for a flight review next.
Currently sitting all my CPL exams again as mine have time expired (completed most in 2009).. 3 down, 4 to go..
I found that re-studying all the theory books/air law has helped after being absent from flying. Doing your CPL subjects should help you out with getting current again also - especially reviewing air law etc..
All the best for getting back in the saddle!
Cheers,
