when tapering legs, the new seams are sewn first then the old seam is removed and the seams are press opened. each of the four seams must be taken in an equal amount. this is so that the pant legs stay balanced. if only the inseam is taken in then the crease will not be centered.
When I do it, I leave the inseam stitched and just stitch a new line tighter in. Try them on inside out to see how they fit, and if they are okay, I undo the original inseam. If it's more than a little bit, I take a little more from the back part than the front since the back part is always bigger and I try to maintain the balance. Once I'm happy with them I re-press the seams and creases.
How to Tailor Your Pants
A sampling of what your local tailor can do.
Length: Pant legs can usually be let down 1 1/2 inches. Ideally, hem pants up two inches maximum (the proportions will be off if more than that is taken up).
Rise: A tailor can take in or let out the rise as long as there is 3/4 inch of fabric to work with.
Pockets: Pockets that gape can be sewn shut or removed.
Waist: A tailor can take in the waist up to 1 1/2 inches at the back or along the side seams. If pants are snug, usually 1/2 inch of fabric can be let out.
Tapering: Slightly narrowing the legs is possible, but you can’t turn bell-bottoms into skinny pants without causing fit issues.
There is a 12-part video on tailoring here. The section on tailoring pant legs starts at part 4.
It's in my earlier post.

Just got done watching it all. She isn't very entertaining, but she does know her stuff.
In part 4 she shows how and where to mark up the tailoring line with pins while the pants are being worn. In parts 9 thru 12 she shows how to transfer those marks to the side seams and how to do the seam ripping and sewing so the end product does not look like the pants have been altered.
