The 4.4 release of FileFly features a new user interface, significant changes to plugins, improvements to AdminCenter, LinkConnect, NetApp, S3, security, and performance enhancements.

See the Administration Guide for thorough documentation on the new version.

Info

Upgrade impacts

  • This upgrade is strongly recommended for all clusters.

  • You should NOT update any existing URIs to use the new URI schemes

  • Due to changes in the Global Licensing Service, once the Admin Portal is upgraded to version 4.0, it is NOT be possible to independently roll back to a previous version (e.g. in the case that agents cannot be automatically upgraded). If attempting to perform this, the message "Software version downgrade rejected - contact DataCore Support" is received from the Global Licensing Service.

  • Legacy statistics reports generated by prior versions are removed during this upgrade

  • Legacy logs and task history are moved to logs\AdminCenter_legacy during this upgrade

NetApp Customers Only

  • ONTAP 9.6 is the minimum supported version.

  • This version transitions to using the ONTAP REST API for FPolicy management. This is necessary since ONTAP 9.12.1 will be the final version to support the legacy Management SDK (ONTAPI).

Changes in 4.4

  • Destination plugins are no longer installed separately.

  • Destination plugin Config Tools and plugin .cfg files are no longer used.
    The Config Tools can be uninstalled completely – plugin selection and configuration is now performed via the Servers page in the Admin Portal.

  • Some scheme/plugin names have changed in this release (see below)
