Not knowing your situation it's hard to answer. What type, cast iron, PVC, brass? Is it on wood over a basement or crawlspace or in concrete? Cast iron on wood over a basement or where you can get to it underneath. You can be gentle, peel out the lead and packing that is holding it in and remove it. You can break the collar and take it out in pieces. Might break the pipe under it if not careful. You can cut the pipe farther down the line and replace it with PVC with a rubber coupler between the PVC and the cast iron. If you just remove the collar, when you replace it, you can just use a repair ring that screwes to the floor. As long as the pipe is supported underneath the floor, the collar does not need to be attached to the pipe.
The collar is called a Tony or Guido collar available at Guido fashions.
