Depends upon whether you want to migrate the V8 databases or whether you
want to start fresh with V9.5. You probably won't be able to use the V8
databases if you don't migrate them ... unless you back them up and
restore them.

Your best bet is to consult the V9.5 Quick Beginnings for Servers Guide
for how to move from V8.1 to V9.5 and for info on the db2_install command.

What happens if you run /usr/bin/pwd from that directory?  Apparently,
that's failing, and the rest of the script just dies from there.

Note that "pwd" and "/usr/bin/pwd" are very different.  "pwd" is the shell
built-in that uses the internal environment to the shell to print out the
current directory, but does not resolve symlinks, or touch the filesystem
in any way; "/usr/bin/pwd", as an external executable, can't access that
internal shell memory, and must touch the filesystem, and, in doing so,
resolves all symlinks to get the real path you're in.  It's that
touch-the-filesystem stage that can confound /usr/bin/pwd.

No.  Check the information center on "Migration" - it should go through the
steps required to move your data from your old version to your new version.
In fact, in order to migrate properly, you pretty much need to keep the old
version around until migration is complete.

(And are you moving from 8.1 or 9.1?  :->)
