I have a Sun Solaris 9 and I would like to clone the Operating System from a sun4u Sun Fire 480R machine to a Sun Fire 280R machine. The disk is the same size, the 480R has no space disk slot to the 280R disk for mirrioring, i have no external disk, I am not allowed to take the machine down.
What is the best way to clone the operating system without any down time?
Thanks in Advance
