"Move" means to go from one location in the realm to a different location in the realm. There are many ways for units in Sorcery to move.
The most common way for a unit to move is the Move and Attack basic ability.
Another way for a unit to move is a forced movement effect, including teleportation.
Notably, if a unit enters a location from a different zone, e.g. summoning a minion from your hand, cemetery, or spellbook, that does not count as moving (though it is "entering"). Finally, note that if a unit tries to "move" from its current location to that same location, it's not actually moving at all.
