To install or upgrade, move your Elastic Stack deployment to version 9.3.6 rather than staying on 9.3.5 or earlier 9.3 releases. Use your normal upgrade path for the products you run, then confirm every component is on 9.3.6. For the exact fixes and product-level changes that apply to your stack, read the release notes for this version before you finish the rollout.
Prefer 9.3.6 over 9.3.5 so you pick up the fixes in this release. Do not treat the upgrade as complete until you have checked the release notes for each product you run and verified that your stack is on 9.3.6. If anything is still on an older 9.3 build, upgrade those components to 9.3.6 as well.
