To install or upgrade, move to Elastic Stack 9.4.3 rather than staying on 9.4.2 or earlier 9.4.x builds. Apply the upgrade for each product in your stack to this same version. Before and after you change versions, read the release notes for the products you run so you know which fixes and changes apply to your setup.
Do not remain on 9.4.2 when 9.4.3 is available, since Elastic recommends 9.4.3 over that previous version. Confirm you are on 9.4.3 after the upgrade, and use the release notes to verify the fixed issues and product changes that matter for your stack.
