Promotion Management Push or Pull?

Hi Pro's,

I would like to know what's the best practice when using Promotion Management in the Central Management Console (CMC) with regards to what server to use to host the Promotion Management jobs. Source (push) or destination (pull) ? 

Lets say I'm migrating folders, reports and dashboards from Development (source) to QA (destination) on the same network, do I:

1. Create the Promotion Management jobs on Development (push)
2. or create the Promotion Management jobs on QA (pull)?

The outcome should be exactly the same.

Environment: SAP BusinessObjects BI Platform 4.1 Support Pack 1

Thanks

Gerrie
