FastPass+ and upgrading tickets

[kiddoc]

I am arriving at WDW on 1/6/2016 and am considering upgrading my current 5 day MYW with park hopper ticket to an annual pass when I arrive. How, if at all, will this affect my current FP+ reservations?

It should not affect your current fp's at all.

Current FP+ reservations will be unaffected.
