This section provides general information such as behavior changes in Solaris 10 OS.
Beginning with the Solaris 10 1/06 release, all x86 based systems must now have at least 256 Mbytes of RAM to run the Solaris software.
Starting with the Solaris 10 1/06 release, you can upgrade the Solaris OS only from the following releases:
Solaris 8 OS
Solaris 9 OS
Solaris 10 OS
To upgrade releases previous to the Solaris 8 software to the Solaris 10 1/06 software, upgrade to any of the releases in the preceding list first. Then upgrade to the Solaris 10 1/06 release.
Although the Solaris 10 software has been tested for compatibility with previous releases, some third-party applications might not be fully ABI compliant. Contact the supplier of these applications directly for information about compatibility.
Your system might run both a Solaris OS and other products that are not part of the Solaris software. These products might be supplied by either Sun or another company. If you upgrade this system to the Solaris 10 release, make sure that these other products are also supported on the Solaris 10 OS. Depending on the status of each of these products, you can perform one of the following options:
Verify that the existing version of the product is supported on the Solaris 10 software.
Install a new version of the product that is supported on the Solaris 10 release. You might need to remove the previous version of the product prior to upgrading to the Solaris software. See the product documentation for more details.
Remove the product prior to upgrading to the Solaris 10 software.
