If you're "only" on NAV 2009 (no SP) and wanna go to NAV 2017, then it's quite a ride. Especially if you're only using the classic forms and reports. The short answer is that there is no tool that brings you all the way. You're crossing quite a lot of generations of NAV, so you need to do it in several steps.
I did a similar upgrade last year from NAV 2009 to NAV 2016. You can go directly from NAV 2015 to 2017 instead.
