Hi all,

We are running around 10 stable instances of IDS 9.21 with lots of 4GL
code written in v7.3 on HP-UX 11.0.

I know, it's really old and long overdue for an upgrade !! We tried for
some time, but de-support of HP-UX 11.0 is finally enabling us to
upgrade the IDS engine.

We want to upgrade our O/S (from HP-UX 11.0 to HP-UX 11.11) and IDS
engine as well.

Considering IBM's 4GL development has stopped at 7.32, which version
would we be better off at migrating, is it 9.40 or 10.0 ?

IBM website does not mention any EOS/EOM for 9.40 or 10.0.

As a techie (I am a DBA), I would like to push for 10.0 but our
management wants a least-complicated way of upgrading. Of course, this
also depends on how our 4GL code and how it goes during system testing.

Are there any catches in going to 10.0 vs 9.40 ? Are there technically
any huge differences in maintaining the two versions ? Can anyone point
me to any realistic resources ?

Appreciate your valuable advice !

Many thanks
Prashant
