We are in the process of upgrading the OS, either from Solaris 8 to Solaris 8, or from Solaris 8 to Solaris 9. The purpose of the upgrade is to convert the 32-bit kernel to 64-bit kernel. It is the production server, and would like to take every precaution there is, to avoid losing data on it. I am wondering if you guys have some experience of upgrading the OS, and the issues that you dealt with, regarding the issue.
Any suggestion would be greatly appreciated.
