We have a few E220R servers that need to be upgraded, but I noticed
that some of the newer Sun offerings don't support 9. We have apps
that only work on 9 and we don't have dev staff to port to newer OS.
What are the choices? I'd like the smallest footprint possible.

First of all, make sure that your application really won't run under
Solaris 10. Most of them should. Sun guarantees upward
compatibility. In fact, I have one application compiled under
SunOS 4.1.3 that still runs under Solaris 10.


That's definitely something that MUST be tested. There is
no hard-and-fast rule that's going to always apply -- Sun's
guarantee or not.

We had an app that did NOT work upgrading from Solaris 2.5
to 2.6. Something significant changed with the X window
libraries we were using. We had to shell out some heavy
dollars in order to get the upgraded IDE we used (TeleUSE)
and re-compile everything.

We've since learned of a viable (and cheap) workaround (copy
over the old X libraries, and point LD_LIBRARY_PATH to them).
But it certainly gave us a jaundiced eye for OS upgrades ever
since.
