To upgrade in place, I'd follow the guide: [Upgrade to Elastic 8.17.4 | Elastic Installation and Upgrade Guide [8.17] | Elastic](https://www.elastic.co/guide/en/elastic-stack/current/upgrading-elastic-stack.html)

About the questions regarding IAAS or SAAS, I'd read [The benefits of a managed Elasticsearch offering | Elastic](https://www.elastic.co/cloud/shared-responsibility) which described where the responsibility is. I personally like a lot SAAS (Serverless as we name it) as it is always running the most advanced version without any operation to do on my side.
