Replying to changing bindings on skis myself

i have bindings on one pair, and i need to take them off and mount them on another pair that IS already drilled. can i do this myslef and is it just a simple matter of unscrewing and then screwing them in on the other pair and then maybe adjusting them a bit to fit my boots? is this safe? or should i jsut pay my local ski shop $25 to do it?

Joe is out of school didnt fucking ask for much Couldnt get a job the marines his last hope Down at the frontline with a gun not a toy Kill many men not asking what for Joe's family the comrades next to him Die one by one his luck is running out Joe wrote back home his parents unemployed The rich is fuckin laughing profits from the war Joe is off to die for another senseless war No arms no legs his mother cries at home Joey wears the flag so proud to fight for us And for a government that doesnt give a fuck
