I would really avoid doing an upgrade like this unless you absolutely HAVE to. The differences between solaris 8 and 10 are quite extensive.

Might be best to wipe clean and start again.

another way to do an upgrade would be "liveupgrade".

If its not gonna be a Live Upgrade, then its called migration..
You have to install Solaris 10. Create similar partitions. Install your apps and test whether it works. You should understand that services are managed using SMF.

solaris 8

Thanks everybody for quick reply.

One thing I forgot to mention that currently there is no load (0 users ) on this solaris machine. I want the old OS as a temp backup for some time . In due course I wish to move to OS 10 only .

I think this is a favourable factor for me . Please share ur isights on this . I am going through the links given by u.

You can perform your OS backup by doing this
df -k <- to check which of your filesystem has biggest available space for your OS
cd /to_spacious_filesystem_dir
ufsdump 0f `hostname`.root.dump /

perform a clean filesystem check b4 you backup Smilie
