Don’t worry. Unless you have placed them on your new room’s access list they will not have auto @’s.
You can also use this command to remove a person’s auto ops:
/chanserv access #RoomName add NickName 0
Change RoomName and NickName to match your own information. This will keep them on the access list but they have no special abilities.
