Transmission fluid help

Hey guys. Need help from some of you experts
This past weekend I installed new cooler lines on my 2010 F150 ( 4.6 140 KM)
So I thought I would drop the pan and replace fluid and filter.
Now a few days later I relize I put the wrong fluid in damit, I see now the truck calls for Mercon LV,
This is the fluid I used apparently only straight Mercon (picture).
I guess my question is can I pump the fluid out of pan and use correct fluid? Not sure how much will still be in rest of system...or should I have the system flushed..
Thanks for any advice.
