cloning configuration from brocade switch

hi all,

its just a quick question more related to the switch side. but i hope someone can help me out here.

i need to clear up zones and aliases from the brocade switch. before doing that i took a clone of the cfg from the GUI.

i removed the zones from the active zoneset, deleted the zone, deleted the aliase, saved the active config and then enabled it.

but i just need to know after deleting the aliases and zones and then incase if i go back to the backup of the cfg taken, will that work?

cloning active config clones everything including the aliases, zones and cfg or just the active cfg ?
