Seeking clarity on upgrade path from OpenSearch 2.x to 3.x

Security

Versions: Opensearch 3.x

Describe the issue:

I understand rolling upgrades are only supported between adjacent major versions .
Does this mean both 2.12, 2.14 and 2.17 require an intermediate stop at 2.19.x before jumping to 3.0.0 or 3.x? Are direct rolling upgrades from 2.12.0 or 2.14.0 or 2.17.0 to 3.x officially supported?

Please provide confirmation on whether direct rolling upgrades are supported for the following version jumps to OpenSearch 3.x:

  1. 2.12.x → 3.x
  2. 2.14.x → 3.x
  3. 2.17.x → 3.x
  4. 2.19.x → 3.x

Configuration: Opensearch Security enabled

@Chandana_EP As per OpenSearch documentation the rolling update is only supported between adjacent major versions.

In this case 2.x to 3.x rolling upgrade is supported.
