Parivartana Yoga is less about a single planet's strength and more about a relationship — two planets that trade places, each sitting where the other rules.
Parivartana literally means exchange or transformation. In this yoga, two planets swap positions: each sits in the sign ruled by the other, rather than in its own sign. The two houses involved are, in effect, mutually invested in each other — whatever affects one house's affairs tends to ripple into the other's, because their lords have traded places.
Parivartana Yoga forms whenever the lord of house A is placed in house B, while the lord of house B is placed in house A — a mutual exchange of signs. It doesn't matter which two houses are involved; any pair of planets that have swapped this way forms the yoga. What does matter, for judging the yoga's quality, is what kind of houses are doing the exchanging.
A Maha Parivartana Yoga: the lord of the 1st house sits in the 9th, while the lord of the 9th sits in the 1st.
Not every Parivartana Yoga is read the same way — its quality depends heavily on which two houses are exchanging. When both houses involved are kendras (1st, 4th, 7th, 10th) or trikonas (1st, 5th, 9th), the exchange is called Maha (Great) Parivartana Yoga, considered one of the more auspicious Raja Yoga-adjacent combinations, since two strong, favourable houses are reinforcing each other directly. When a good house — a kendra or trikona — exchanges instead with a dusthana (the 6th, 8th, or 12th house, houses of difficulty), the result is called Dainya (Deprived) or Khala (Mischievous) Parivartana Yoga. Here the good house is classically described as "sacrificing" some of its strength into the difficult house, producing a generally mixed-to-challenging outcome rather than a clean benefit. An exchange between two ordinary, less pivotal houses that are neither kendra/trikona nor dusthana is generally read as a comparatively neutral Parivartana, with milder effects either way.
Beyond the house types involved, the individual strength of the two exchanging lords shapes how the yoga plays out. Two well-placed, undamaged planets exchanging between good houses give the fullest expression of a Maha Parivartana's promise. If one of the two lords is severely afflicted, even a kendra-trikona exchange can underperform its classical promise, and conversely a well-managed Khala Parivartana can be far less disruptive than the name suggests.
An exchange of signs is a partnership, not a placement — and like any partnership, its value depends entirely on who's involved.

No. Its quality depends on which houses are exchanging. A kendra-trikona exchange (Maha Parivartana) is highly favourable, while a good house exchanging with a 6th, 8th, or 12th house (Khala or Dainya Parivartana) tends to give mixed or challenging results.
Not directly for formation — the yoga forms purely from the mutual exchange of signs regardless of whether either planet is exalted or debilitated elsewhere. However, the strength of the two exchanging lords still shapes how fully the yoga's promise plays out.
It's a classical way of describing how a favourable house's lord, sitting in a difficult (dusthana) house, effectively lends some of its own good significations to that harder house — softening the dusthana's difficulty somewhat, but at some cost to the good house's own clean expression.
Yes. A chart can have multiple independent pairs of house lords that have each exchanged signs with one another, forming more than one Parivartana Yoga at once.
A conjunction or aspect involves planets sharing a house or casting influence on each other from a distance. Parivartana is specifically about lordship — each planet physically occupying the sign the other one rules — which is why it's treated as its own distinct category of yoga.
