Upgrade from 4.0.1 on NT to 4.7 on AIX

Hi everyone,
We are currently using WebMethods 4.0.1 on NT and we wanted to migrate to 4.7 released by SAP for AIX. I was wondering if anyone ever did and upgrade from NT to AIX while using WebMethods. Pl let me know. Even if you had finished upgrading from 4.0.1 to 4.7 on the same operating system, If it is possible I would like to know more infomation about the performance results and the memory utilization and any issues that you faced along any comments and concerns are appreciated.

You can email me at c-rkongara@state.pa.us

Thank you
Ravi Kongara
