It depends a lot on the application platform that you are using. HPUX
has been running on Itanium for some time now, most applications run in
32-bit mode without changes, however to take full advantage of the new
architecture, the database and compilers need to support the 64-bit
processing.

Subject: [HP3000-L] long live PA/RISC; questions about migrating HP/UX
PA/RISC to ITANIUM

Robelle's monthly newsletter directs its readers to an article about the
long expected "demise" of PA/RISC:
http://www.siliconvalley.com/mld/siliconvalley/11778798.htm

I quote from the article:  "HP plans to sell servers running the older
generation of chips and its version of the Unix operating system, called
HP-UX, for about three years. It will also provide customer support for
the systems for five years after that, or until about 2013."

Commentary:  HP3000-L readers will notice that the article does not
mention the HP3000 family of systems.

Questions:  Is the migration of HP/UX on PA/RISC to HP/UX on ITANIUM
seamless, from the point of view of software compatibility?  Are the
data
structures and high-level constructs essentially identical to in-house
application programmers?  Is it true that those who have opted to
install
HP/UX PA/RISC systems must now consider thinking about a migration to
ITANIUM?

Facts, Comments, and Opinions are welcome!  Thank you.
