I have a DB2 UDB Server V8.1 WSE for AIX. Now, I want to upgrade the DB2 instance from WSE to ESE (64-bits).

It seems to me that the command "db2iupdt" can change the instance from 32-bits (WSE) to 64-bits, but this command does not have option to change the instance from WSE to ESE.

So, do I need to drop the existing WSE instance and then recreate the instance (by db2icrt) with the instance type (ESE) and wordwidth (64 bits)?

Pls advise.

Thanks

Hi Wong

As far as I'm informed the only distinction between
WSE and ESE is the amount of processors allowed

So the way to go to ESE is buying a license for more
than 2 processors and using the db2licm command to
update your licenses

You can use the -? switch to see options

After OR before that you can update your instance or create
a new one concurrently for test purposes - you can run 32 and 64
bit instances on the same machine

Good Luck
