Post Operating System Upgrade Tasks
Below is a list of tasks or items that may need to be checked after a Solaris Operating System upgrade.
1.) DNS – if upgrading from BIND 4 to BIND 8 (Solaris 2.6 to Solaris 8) you will need to run the “named-bootconf “ utility to convert the named.boot file to named.conf.
2.) Sendmail – verify sendmail still works. If not, find out what’s changed & apply any configuration changes.
3.) VCS Clustering – During the Hub upgrade, I had to remove & reinstall…
4.) ndd settings for network interfaces. These settings are most likely removed from /etc/rc2.d/S69inet during the upgrade process. The entries should be put back, but put the entries in /etc/rc2.d/S70nddconfig.
5.) Most importantly is to make sure when you boot the system, you get a clean boot with no error messages. This may take some time, but it is well worth the effort, so open support calls to whatever vendors, install additional patches (maybe upgrade existing patches), etc. Do what it takes to get a clean boot.
6.) Move back and key files that you copied, like /etc/system, /etc/hosts, /etc/defaultrouter, …
7.) Upgrade other 3rd party software products like Patrol, top, etc….
