gear shifter moving

i have a racing bike, an old pergeot frame that i might give to my girlfriend and it has 5 gears, but she hates using drop bars and said i would take off the drop bars and put on standard risers, is it easy to move the shifter (or in deed wise) from the drop bars to a normal position on risers? its not a touring bike so the shifter isn't on the frame, however may i need a different shifter or can i use the same one? i think its a trigger shifter as well

What sort of shifter?

Is it built in to the brake levers or is it two levers bolted around the stem?

i think its bolted around the stem, from the picture my old girl took of it, the wire finishes at the stem

if thats the case then the risers can be put on and the stem left with the gears on right?

Stem shifters are found on a lot of basic 70's/80's adults bikes.

The key here, is that it is on the stem. So if you change the handlebars, the shifter will still be on the stem and just as usable as it was in the first place.

ooh, i was a little slow with my reply.

Precisely, you are correct.

but say if it was on the drop bars and it was a trigger or lever, is this rectifiably easily?

Ive never seen bar mounted shifters on drop handlebars before, but in the rare incidence that the bike has one, theres no reason why you couldnt slide it off and fit it on to the replacement flat bars.
