SUM 1.0 SP14 03, How do I start multiple processes of SUM on the same host?

Hi,

We have a BW DEV ABAP system and a BW DEV Java system on the same host. We would like to run SUM in parallel, or at least run the preparation phases in parallel. In previous SUM version (i.e pre SP13) you could STARTUP with httpport syntax to run it on a different port, hence starting several parallel SUM processes, but how is this working on SP14 and the new way of starting SUM using STARTUP confighostagent <SID>?
