My UNIX admin is on leave for new year and I want to do this by my own..I wonder if you actually understand the complexity of your task. There is no way you can get any useful hints based on the limited amount of information you have provided, nor will a couple of forum posts teach you what is necessary to understand. Perhaps you might want to reconsider rushing into this and causing unnecessary problems.
