If you are upgrading from an existing version of Solaris and have installed unbundled products, either from Sun or from a different company, you must ensure that all those products are supported on Solaris 7 prior to upgrading. Depending on the status of each unbundled product, you have three options for each unbundled product:
Verify that the existing version of the unbundled product is supported on Solaris 7.
Acquire and install a new version of the unbundled product which is supported on Solaris 7. Note that in this case you may need to remove the previous version of the unbundled product prior to upgrading to Solaris 7. See the unbundled product documentation for more details.
Remove the unbundled product prior to upgrading to Solaris 7.
For additional information contact the supplier of the unbundled product or your service provider or go to:
