Need to move toilet

I am remodeling my bath and want to move the toilet sideways. I've seen offset flanges,, but not sure how well they work or what the max offset wold be. also I don't want to make the toilet have problems flushing.
I am on a slab, and I can cut out the concrete, I just don't want to end up with a huge project trying to get the toilet flange and pipe hooked bck up. I am pretty sure the pipe runs parallel to the direction I want to move the toilet in so tha the pipe will need to be cut shorter The house is about 23 years old, so I am pretty sure the the drain pipe is somewhat modern material. ABS or?
Any input would be appreciated. Joe

toilet

You will not know the material until you remove the toilet, and the same is true of the drain's direction. Until you have facts you will not know what to do or how to do it.

Thanks for that reply. Any thoughts on the offset flange idea? Joe

offset

Depends on the material and the flange. Some offsets are no worse than a regular one, while others are a disaster, either to install or during use. And some will not offset sideways.
