Migrating to Podman 5

Following are the supported upgrade paths for Podman 5 in Elastic Cloud Enterprise.

^* Supported but not recommended given that a newer version (Podman 5.2.2-13) is available.

Podman 5.2.2-13 is only supported when conducting a fresh Elastic Cloud Enterprise installation or performing a grow-and-shrink update from Docker or Podman 4.

For in-place updates, it is recommended to use Podman 5.2.2-9, since upgrades to versions 5.2.2-11 and 5.2.2-13 are affected by a known memory leak issue. When performing an in-place update, please make sure to configure the Podman version to be locked at version 5.2.2-9.*, by following the instructions below.

## Install versionlock
sudo dnf install 'dnf-command(versionlock)'

## Lock major version
sudo dnf versionlock add --raw 'podman-5.2.2-9.*'
sudo dnf versionlock add --raw 'podman-remote-5.2.2-9.*'

## Verify that podman-5.2.2-9.* and podman-remote-5.2.2-9.* appear in the output
sudo dnf versionlock list

Podman versions 5.2.3 and higher are not supported.
