Solaris Web Start Post-Installation and Upgrade Tasks
After you install or upgrade the Solaris operating environment, you might need to perform these tasks.
To Correct Local Modifications After Upgrading
When you upgrade, the Solaris Web Start program merges local software modifications of the existing system with the new Solaris software. However, in some situations, merging is not possible. After you finish upgrading a system, you might need to correct some local modifications that were not preserved.
Caution - Your system might not boot if you do not correct the local modifications that were not preserved.
