Hi Axil
I have upgraded from 6.9 (source) to 8.5 Omnibus. I got stuck many places. I have briefed my upgrade path in one of the questions in the community. Could you please Review it and let me know your comments.
I want to contribute the issue you have opened, please let me know how can I contribute to the documentation.
Please review this
