General Advisories
The information in this section provides general advisories about important aspects of this release. To ensure proper operation of the system after upgrade, you might need to take account on these advisories.
Supported Operating Systems
The 21.1.0 PCE and VEN are supported on operating systems detailed on the Illumio Support portal.
See PCE OS Support and Package Dependencies and VEN OS Support and Package Dependencies.
Be Sure Prerequisites and Settings are Correct Before Installing
The PCE Installation and Upgrade documentation contains detailed information about required prerequisites and settings. Always follow these instructions precisely to be sure your PCE continues to function properly over time.
Important documentation changes have been made in this area for 21.1.0. See the PCE Installation and Upgrade Guide for information.
Before Upgrading to This Release
Before upgrade, review all changes from your current version to version 21.1.0.
To ensure readiness, Illumio strongly encourages you to review the prior release notes, from your currently installed version of Illumio Core to version 21.1.0. To view the release notes for versions prior to Core 19.3.x, go to the Documentation page on the Support portal (login required) and select the version from the drop-down menu.
For information about the upgrade path and tools, go to the Illumio Support portal and review the PCE Upgrade paths and the VEN Upgrade paths (login required).
Preview Features
Any preview feature of the Illumio Core is for your evaluation only. The purpose of preview features is to make them more useful for your organization's needs before general availability.
Do not deploy preview features in a production environment.
To avoid inadvertently impacting your current system, install preview features only in a non-production environment.
Illumio welcomes your comments and suggestions for improving preview features and documentation. For more information and to send feedback, contact Illumio Customer Support.
Manage Data and Disk Capacity Carefully
Beginning with PCE 18.2, the amount of data collected and stored by the PCE has increased. Events, Explorer, and the internal syslog all generate more data to be stored in PCE databases and log files. If the amount of stored data is not managed carefully, disks can become overfull, or backup size can increase, making restores take longer.
To successfully manage these concerns, consider the following:
- Identify: Know your organization's policies, backup strategies, and monitoring strategies.
- Detect: Monitor ongoing disk usage.
- Respond: Know how to troubleshoot and fix issues related to data storage.
- Recover: Set up your PCE deployment to reduce disk usage.
For more information, see Manage Data and Disk Capacity in the PCE Administration Guide.
Supported Supercluster Configuration
In this release, Supercluster support is limited to 3 PCEs with 25k VENs per PCE (4x2 configuration).

End of Life
Virtual Appliance
The PCE Virtual Appliance will no longer be published, and you can no longer deploy a PCE using the Virtual Appliance.
End of Support
Illumio REST API v1
The version 1 of Illumio REST APIs (API v1) is not supported effectively with the 21.1 release. Illumio recommends that you upgrade to API v2.
Internet Explorer 11
Illumio Core 19.1 was the last release to support Internet Explorer 11. Internet Explorer 11 will no longer be supported in Illumio Core 19.2 and later releases. Illumio recommends Chrome, Edge, or Firefox for use with the PCE web console.
External VEN Repo
The external VEN repo is no longer supported for VEN versions 18.2 and later releases. Customers must migrate to using the new PCE-based VEN deployment or install VEN packages directly on workloads.
System Events for OVA
Events 2.0 system events are no longer supported. (For reference, see E-48119)
Organization Events
Since the 19.1.0 release, the older form of events, known as “audit or organization events,” is no longer supported or available.
Any versions of the former SIEM Integration Guide that are earlier than version 18.2.1 are valid only for their corresponding versions, not version 18.2.1 or later releases.
Customers should upgrade to the latest version of Illumio Adaptive Security and take advantage of the newly designed auditable events. See the Events Administration Guide for information.
Deprecation
Runtime Environment File Parameter
The runtime environment file parameter syslog_event_export_format is deprecated.
Network Function Control
The Network Function Control (NFC) was discontinued in the 19.3.0 release. It is now a part of the Network Enforcement Node (NEN). You can use the NEN module to interface with the F5 Server Load Balancer. For more information, see the NEN Installation and Usage Guide.
