Hi,
We are on Windows on v7.5.3 and are planning to migrate to Information Server V9.1.2. Currently the Datastage Engine is 32-bit where as I understand in 9.1.2 it will be 64-Bit (or 32-bit?)
Are there any potential issues due to change in bitness that could impact the export/import/compile of the server jobs in the new version?
Appreciate any insight into this.
Thanks,
VN
32-Bit to 64-Bit - Datastage Version Migration

Any issues you encounter with upgrading the jobs should be unrelated to "bitness". The only time I've encountered any "32-bit" vs. "64-bit" issues was with custom routines that required some tweaks to compile correctly with 64-bit libraries.
There are quite a few issues you will encounter during that significant of a jump between versions, but they will be related to the many new features and new restrictions / policies. You will also encounter issues if the site decides to turn on NLS support, which will cause jobs to respond differently when out-of-map characters are encountered.
In summary - don't expect the jobs to just compile and run...
Also - be sure to install the 64-bit database client / drivers to maximize performance.
