OSM version recommendations?

I have noticed a couple of OSM versions have been mentioned in posts, however, which version would be most recommended to install for local testing to be compliant with 5GASP platform and to be able to run the NetApp later via the 5GASP? Thanks.

You should start with at least OSM10 which supports ETSI SOL006 (https://www.etsi.org/deliver/etsi_gs/NFV-SOL/001_099/006/02.07.01_60/gs_nfv-sol006v020701p.pdf) alongside with OpenStack and Kubernetes that serve as main deployment platforms within 5GASP environment.
