It must undergo heat and pressure. Different amounts for different rocks.
compaction
As in what process causes this? if so it is usually under heat and pressure. Depending on what kind of rick it is depends on the resultant metamorphic rock e.g Shale-->Slate etc
It must weather and erode, forming sediment that can eventually lithify into sedimentary rock.

It must melt.
No, not all stones can start out as metamorphic. Metamorphic rocks are formed from existing rocks that undergo high heat and pressure, so they must have a pre-existing rock to transform from.
what processes must sedimentary rock go through to become a metamorphic rock
what processes must sedimentary rock go through to become a metamorphic rock
Metamorphic rocks are formed from existing rocks that undergo changes in temperature, pressure, or chemical reactions due to processes like heat and pressure from deep within the Earth's crust. These existing rocks can be sedimentary, igneous, or even other metamorphic rocks that get transformed into a new type of rock.
To become a sedimentary rock, an igneous rock must first be weathered, and then eroded, and then deposited as a sediment, and then consolidated (e.g. by cementation or pressure welding of grains.) To become a metamorphic rock it must be transformed by heat and pressure, which it can do directly (e.g. granite turning into gneiss) or after first turning into a sedimentary rock.
Sedimentary rocks must be subjected to high temperature and pressure within the Earth's crust to become metamorphic rocks. This process, known as metamorphism, causes changes in the mineral composition and texture of the sedimentary rock, resulting in the formation of metamorphic rocks.

It must be false, because the statement in question is not valid all the time. Sedimentary rock might become metamorphic rock after millions of years, but it might take less time, more time, or not happen at all.
