Support for online migration from Ext4 or XFS to VxFS

The online migration feature provides a method to migrate a native (source) file system to the VxFS (target) file system on the same host. This method takes minimum amounts of clearly bounded, easy-to-schedule downtime. Online migration is not an in-place conversion and requires a temporary, separate storage.

During online migration the application remains online and the native file system data is copied over to the VxFS file system. Both the file systems are kept in sync during migration, which makes online migration back-out and recovery seamless. The online migration tool also provides an option to throttle the background copy operation to speed up or slow down the migration based on your production needs.

This feature was already supported for migration from Ext4 to VxFS; from this release onwards the support has been enhanced to include:

  • Migration from XFS to VxFS on the same host
  • Migration from either Ext4 or XFS to VxFS over NFS v4
