Has anyone figured this out?
I have a similar situation, and I know it can be done because the previous SysAdmin did it. We have 2 machines (let's just call them T1 & T2). We had RedHat 7 installed on T1 and RedHat 8 installed on T2. Both machines had iPlanet 6.0 SP8 running.
We upgraded T1 to RedHat 9 and restored the /usr/iplanet/servers directory, then tried to start iplanet. Result:
./commit: relocation error: ../../lib/libnsres30.so: symbol errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
I know that simply restoring the /usr/iplanet/servers directory was only a shortcut, but now it seems there is no guarantee that iPlanet will work if I install fresh off the CD.
