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.
