Unity OE Matrix

Our Recommended Code (Target) is shown in bold. This is a highly trusted and recommended release that is evaluated against criteria including runtime time in the field, number of installations, quality metrics, and so on. Recommended Code (Target) and Latest Code released can both be the same revision level if the right criteria have been met.

Unity OE supported upgrade paths

Some Unity OE upgrades cannot be done directly and require intermediate upgrade steps. This table describes the valid upgrade paths.
Unity systems running versions older than 5.1 must upgrade to 5.4.1 before upgrading to version 5.5. 
This is due to changes in support for TLS, KMIP, and encryption keys between the pre 5.1 versions and 5.5. See the New Features section of the Unity OE 5.4.1 release notes for more details.

Table 2: Unity OE supported upgrade paths.

Note: If you attempt to perform an unsupported upgrade when a double-hop upgrade is required, an error message is shows as the encryption keys are not available to decrypt the upgrade package:

Notes

Note 1 - Unity systems shipped with OE version 4.1.0.8940590 (Factory-only version) come with this note: Due to an issue found in Unity OE (Operating Environment) 4.1.0.8940590 (currently loaded on this Unity system) we recommend upgrading to the latest Unity OE version upon install of your new system.

Note 2 - Unity XT (x80/F models) was released in the same day as Unity OE 5.0.0.0.5.116. Unity OE 5.0 and later releases are compatible with the existing Unity models x00/F and x50/F, as well as the new x80/F models (Unity XT). Note however, that the new x80/F models require a minimum of Unity OE 5.0.

Note 3 - There is a requirement to disable TLS 1.0/1.1 and enable TLS 1.2 before performing an upgrade to Unity OE 5.5. See Dell Unity: Alert 14:b20080 TLSv1.0 and TLSv1.1 are not secure. It is recommended that you use TLSv1.2 and Dell Unity: How to Disable TLS 1.0 and 1.1 on Unity Array for details.

List of available Unity OE Hotfixes

Notes:   

• If a more recent code is available that already contains the required fixes, upgrade to that code instead of installing a hotfix on older code.
• Minor or specific hotfixes (one-off HFs, or HFs for specific customers) are not listed here. 
• Only hotfixes for our recommended code and later are shown here. All other older hotfixes are not shown in this matrix.
• Do not install hotfixes without confirming with an SME or Engineering.
• ATTENTION: All hotfixes below are full upgrade images. Any previous Unity version can be upgraded to these hotfixes directly (it is not required to install the base code first and then the hotfix).
• Since these hotfixes cannot be uninstalled or downgraded to earlier versions, the only option is to upgrade to a later version (but it is an older version). Roll-Back hotfixes are available for customers that request a Roll-Back strategy. Engineering must be engaged for this.
