Migracion 7332 to Xe: Can systems operate parallel?

Hi Everybody,
I have to do a migration from 7332 to Xe (Win2K Deployment, RS6000/AIX Data and Enterprise Servers, Oracle 8.1.7). There are some custom applications and UBEs. The migration will not move the systems from the current servers, that is, the old Enterprise server will also be the new Enterprise server, etc.

Once I am done with the migration, they want to use the two systems in parallel for a while to make sure the two systems both do the same thing. Is it a problem to use the two systems in parallel? If it can be done, are there any special considerations to take into account? Mostly we are concerned about running the Enterprise and Data Servers in parallel, but it would be nice if the workstations could have both OneWorld 7332 and Xe cfat clients installed.

Thanks in advance.

Tim :

They can use systems in parallel as long as they use different environments.
tables, these tables won't be readable by B7332!
If I were you, I would do the following :

Before migration
Copy PRODB733 (B7332) to a custom environment PRODCOPY (with its own
Business Data and Control Tables datasources)
After migration
On Fat clients use SNAPSHOT.EXE to switch among B7332 and Xe clients, B7332
would be pointing to PRODCOPY environment (check P0092)
while Xe clients would be using regular PD7333 with migrated data.

Best Regards, Sebastian Sajaroff

Tim,
you can run the services of two releases of OW, say B7332 and Xe, on one
server in parallel. Most Datasources are per release, for example DDB733
(B7332) vs DD7333 (Xe), so no problem there either.
The problems would be Business Data - Prod and Control Tables - PROD . The
business data get updated (Table Conversion) in place during upgrade.
To run two versions of OW in parallel in production you would need to create
an extra set of Business Data, like Business Data Prod_1, and run that for
your old system. Same with Control Tables. After you are confident that you
do not need them any more just drop them.

Create the copy of BS-Data and CTL Tables just before you run the table
conversion, with everybody off the system.

Good luck, Gerd

Tim,
Check the service pack level of your C compiler. Is it 6 on the B7332 box ? If it 5 you will need to upgrade to 6 when you install XE. And that of course would mean freezing any development in the B7332 environment until the upgrade is complete.
