Upgrading Solaris 8 to 64 bit

2007-12-25 6:18:00

I am trying to upgrade my 32 bit Solaris 8 installation to 64 bit. I don't
have the original installation media, I downloaded the latest Sol 8 isos
but when I boot from CD I am not given the upgrade option, only initial
install. Does anyone know what packages I need to install to enable 64
bit? System is an E250 with a single 400Mhz ultra II processor.
TIA,
Steve
