Transform objects

Hi guys - amateur here - I recently had an objects mesh/texture altered for me - my idea was to just replace the old with new using the transform menu - I selecting the object to replace and used ‘copy to selected’ - now both objects have the same transform details but are sitting in different locations?

It will be good to post some images or .blend file because it is really hard to help with so few information.

Hi Erik - thanks for the comment - will do in the future - I figured out a work around - I centered the curser in the object I wanted to replace and then got my replacement object to center to the curser - I then rotated to refine - not perfect but close enough.
Still confused though how two identical objects can have the same transform details and yet be in different locations and angles.
