Update lifecycle policy

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

You can update an existing lifecycle policy to fix mistakes or change strategies for newly created indices. It is possible to update policy definitions and an index’s index.lifecycle.name settings independently. To prevent the situation that phase definitions are modified while currently being executed on an index, each index will keep the version of the current phase definition it began execution with until it completes.

There are three scenarios for examining the behavior updating policies and their effects on policy execution on indices.
