Ankush, Upgrades between major versions are supported by the infrastructure described in the following specification: https://docs.starlingx.io/specs/specs/stx-4.0/approved/starlingx-2007403-pla... However, the starlingx community does not test or support upgrades (this work is done by commercial products that build on top of starlingx). To do an upgrade, you would need to do your own upgrade testing and fix any issues you uncover. Upgrades often require additional changes on the "from" release side, so you would likely need to build your own patches as well.
