--- prelude: > The share migration feature was improved to support migrating snapshots where possible and provide a more deterministic user experience. features: - Added 'preserve_snapshots' parameter to share migration API. upgrade: - All share migration driver-assisted API parameters are now mandatory. - Improvements to the share migration API have been qualified with the driver assisted migration support that exists in the ZFSOnLinux driver. However, this driver does not currently support preserving snapshots on migration. - Snapshot restriction in share migration API has been changed to return error only when parameter force-host-assisted-migration is True. deprecations: - Support for the experimental share migration APIs has been dropped for API microversions prior to 2.29. fixes: - Added check to validate that host assisted migration cannot be forced while specifying driver assisted migration options. - The share migration API can only be invoked when at least one parameter within (host, share-network, share-type) is expected to be changed.
