Minecraft wiki entry for Nether_survival, associated text: Villagers can be brought into the Nether through a portal, either using a boat or minecart. Make sure the portal is protected, so ghasts don't fireball you or damage the villager. Villagers can use beds without blowing them up, allowing for artificial villages and iron golem farms to function properly. They do run away from zombified piglins even though zombified piglins don't attack them.
