How versioning and transport NW BPM in PO7.40

Hi all

we plan to use NW BPM in PO 7.40, however PO7.40 is the only Java component in our landscape, there is no other Java stuff. Thus there is no NWDI setup and we do not intend to install NWDI.

Now the question is how can we versioning BPM without NWDI DTR, and how can we transport BPM to QA / PRD?

as for transport, I guess we can just deploy BPM from NWDS to QA / PRD (certainly not the good way). As for versioning, I absolutely have no idea how to do without NWDI.

Anyone can shed some light on this? is it possible to properly DEV NW BPM for PO7.40 without NWDI? if yes, how you've done it or suggest?

Thanks

Jayson
