Discussed on May 19th initially: Sam K agreed to take it up and discuss with core team to assess impact and next steps and report back to the DA.

May 26th 2021: Discussed on the DA call and made the below proposal

• Since node v12 LTS support ends only in April 2022, we'll continue with helm v12.1.0 with node v12
• After the helm release, as part of maintenance, as we touch a core service, we'll upgrade it to v14 LTS version and reassess the situation
• If straight forward, continue with upgrading rest of services
• else propose that this upgrade be done as part of Ref.Arch work-stream (developing the vNext of ML core), since thats a huge refactoring anyway
• Need to set a reminder around October timeframe to remind adopters / implementers to ensure everyone is upgraded to latest versions of services (and that the services themselves are upgraded) that use v14 LTS

This proposal was accepted by the attendees on the call but if you have further comments/feedback, please post here or reach out the the DA

I believe we should update this issue to upgrade Node v12.x to the latest current LTS supported version - which is currently v16.x (released 2021-04-20).

Note: I would recommend that we only consider "even" versions since uneven versions do not enter long-time support with support being dropped after 6 months.
