Upgrade to Solaris 2.4/2.5
I am considering upgrading Solaris 1.1.2 that is currently
installed on our servers to Solaris 2.4 or 2.5.
Please mail me any problems that I may find and whether
Solaris 2.4 and 2.5 are stable.
----------------------------------------------------------
Summary of comments:
Solaris 2.5 is more stable than Solaris 2.4. It also has
interesting new features such as CDE, and it has Dynamic
IP Addressing, CHAP and PAP. 2.5 is running well on all
systems that have been upgraded, in contrast to 2.4
that has created problems until patch cluster were
released from Sun.
Many administrators recommended 2.5 being more powerful
than 1.1.4 that I am working with. Some pointed out that
if I do not need (or will not use) the features implemented
in 2.5, then I should simply remain with 1.1.4. Upgrading
to 2.5 means that the public domain stuff has to be
recompiled, the shell scripts have to be revised and updates
have to be purchased for third-party software,
This is a very brief overview what to consider when upgrading
from Solaris 1.1.x to to Solaris 2.5. The overall lesson is
that the software installed on the machine is the problem
to upgrade, not the OS itself. Re-configuring the third-
party software can take months of hard work until the machine
becomes stable again.
Many thanks to all those who replied and gave me links
to sites where I can get more information
