I have an IA64 version of DB2 and I'd like to go directly to 64 bit without passing go but there are a few problems. You see, I have about 300 databases currently running under version 7 db2. Version 8 DB2 client doesn't work completely right with version 7 databases. Version 7 client won't work with a version 8 64 bit database. It will work with a 32-bit version 8 database however.

So, I was hoping to do a 2 phase migration. First upgrade all my 7 db's to version 8 32-bit. (And while this process is in progress, all my version 7 clients will still happily work on all the new version 8 32-bit db's and all the version 7 databases which haven't been migrated yet). Once I've migrated all the version 7 databases to version 8 (32-bit), then I can upgrade all the clients to version 8. Then I can turn around and migrate all the 32-bit databases to 64-bit. Convoluted? Yes. Unfortunately the best way I can think to do this.

Does anyone have a better idea?

Wise,
You can run IA32 application on IA64 by the help of IA32EL. Because this IA32 application run as an MRTE application just like Java & .NET ones so the high performance of Itanium would not be brought out.
I sugggest that you should get an IA64 version of db2 and migrate your application to this platform, the process will be very easy and straightforward.

Subject: 32-bit Instance on Itanium

I've got an Itanium box running Red Hat Linux here and it doesn't seem
possible to create a 32 bit instance. (Every time I run db2icrt -w 32,
I end up with a 64-bit instance anyway). Anyhow, could anyone confirm
whether or not it is possible to run a 32-bit database instance on
Itanium/Linux?

Thanks,
Greig Wise
