You don't have to control either target permanent. |

Gaining control of a permanent doesn't cause you to gain control of any Auras or Equipment attached to it. |

The permanent types are artifact, creature, enchantment, land, and planeswalker. Supertypes, like legendary, aren't permanent types. For example, you can't exchange control of a legendary creature with a legendary planeswalker. |
