What does replacing mean?
Replacing means putting one person or thing in the place of another, usually because the original is no longer useful, has failed, or needs to be superseded. It can describe replacing a component, updating old equipment, substituting one worker for another, or allowing a newer product or system to take the place of an older one. As the present participle of replace, it appears in progressive constructions such as “is replacing” and can also precede a noun, as in “replacing parts.” The word is common in both formal and informal English across Britain and the United States, although its more technical uses often concern equipment, personnel, or outdated systems. It differs from replacing in the sense of merely moving something: replacing normally emphasizes substitution or substitution with a new version, whereas placement may describe the movement alone.
To substitute one person or thing for another, or to put something new in place of something old, damaged, or unsuitable.
"The hospital is replacing its aging scanners with newer equipment."
Usually the present participle of replace; it can follow forms of the auxiliary be or stand independently before a noun.
Serving as a temporary or newer substitute for an original person or thing.
"The replacement unit remained operational while the main engine was repaired."
Replacing brings the Latin prefix re-, meaning “again,” to place, reflecting the idea of putting something back in position or substituting it for something else.

Where does replacing come from?
The underlying verb replace comes through Middle English from Old French replacer, a formation based on Latin re- and placere, meaning “to place.” The prefix re- contributed the idea of placing again or putting something in a new position, while the modern meaning developed toward substitution. Cognates such as replacement and displacement preserve the same Latin placement root.
