Does anyone have any horrors stories or advice for upgrading from Solaris
2.6 to Solaris 8 with volume manager 2.6 (we will be upgrading to 3.5 before
the Solaris upgrade) before I go and perform it on a live production server
?

Thanks.

You need swags of space in /usr. Cant remember exactly how much but a
colleague of mine called sun and asked .. they said ~1gb and he made
sure there was 1.5gb and it still failed !

you may want to talk to sun.

If by Volume Manager you mean DiskSuite, forget it. The earliest
supported release for Solaris 8 is 4.2. Why not go the whole hog,
and upgrade to Solaris 9, with its built in Volume Manager?

Hey,

look in the Solaris 8 Packages and install SUNWluu and SUNWlur. With
this Package
it is able to perform a "live upgrade". That means, you need another
new bootdisk, lu will install the old OS on it and then upgrade with
the new
packages. It is supported by SUN an it really works!
To upgrade the volume manager there is a little trick, but you can do
it in
the same time. All you need is in fact a downtime for three reboots.
And - if the upgrade fails - you can switch to the old installation
and boot
from here.

found it was much easier to back all the data up, wipe the 2.6 machine,
install 8, then reinstall all the data and apps. If you're good at
scripts and have a few months to play in a lab, this should hurt too
badly. and if you can't reinstall your apps from scratch in a timely
manner, it may be a good example of a potential weakness in disaster
recovery plans.
