This finally solves the problem with the old and new rulers (Saturn-Uranus Aquarius, Jupiter-Neptune Fish, and Mars-Pluto Scorpion).
In regards to the lights of life (Moon - Sun), there are some justified doubts about such an exchange. Astrologers were, for example, always convinced that Jupiter, by way of Pisces, had a domicile, but not that the Moon had one by way of Leo. This would mean that the Moon in Cancer has a 1st and 2nd domicile. The same holds true for the Sun in Pisces. Thus, the 2nd domicile is not aligned to the same perfection that the 1st domicile is.
One already knew seven allocations (Venus-Taurus, Moon-Cancer, Sun-Leo, Mercury-Virgo, Mars-Scorpio, Saturn-Aquarius, Jupiter-Pisces) in the classical astrology. Five allocations (Uranus-Capricorn, Neptune-Sagittarius, Pluto-Aries, Faunus-Libra, Iustitia-Gemini) are new. In the countersigns one can find the 2nd exile.
The 2nd domicile is the second most important dignity of the planets. It is here that there are the second-most similarities between the planets and the zodiac signs. This arrangement emerged in 1974.
