Backup or flash archive. Pls suggest correct way.

Hello mates,

There is a task of Sol 10 installation and configuration of it by customer's demands on a few Solaris boxes (SPARC).
The boxes have different capacity of IDE disks and one root ufs file system per box.

I have completely prepared one of them. It took couple of days.
"Completely prepared" means OS installation, individual host name, IP-address, user environment setting, few applications installation with needed version. A test, whether working it is all together properly or not.

A question...
Am i right? I have to create flash archive in this case?
Could somebody explain in details how to do it?
Also I am interested in whether there is any possibility upload flash archiv to windows machine and in case of necessity to do installation of archive for the next SPARC box over the network. Just how to do it if it is possible?

Thanks in advance.
