If you don't have support I wouldn't go for solaris 11 now... Solaris 10 is a very mature product and latest version run pretty smooth.

To migrate 9 to 10 use Live Upgrade, I've done it many times and works perfectly... you might face some problems depending the installation and the customization level but in general works very well. You can follow this procedure

Upgrading from Solaris 9 with a Root SVM Mirror to Solaris 10 with a Root ZFS Mirror with less than 10 Minutes of Downtime

For Solaris 8 have you consider running them on solaris 10 branded zones?

If the application works fine then it might not worth to do such a move, you either reinstall and reconfigure to solaris 10 or run the whole OS on a zone. Of course that's my personal opinion, you could still go through the upgrade path.

For your needs I think Live Upgrade is the best path, if you run into problems you can always boot from the original boot environment. You can either use the DVD and select the upgrade option.

Should I mention backup is always a good idea no matter what you use...

Any question let us know... cheers Juan

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris  invokes  the  Solaris  Install  program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

           Minimum physical memory for all installation types

       128 MB

           Minimum physical memory required for windowing system

       384 MB

           Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

           Minimum physical memory for all installation types

       256 MB

           Minimum physical memory required for windowing system

       512 MB

           Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.
