After you upgrade to VMware Identity Manager 2.8, configure these settings.
If you have set up a VMware Identity Manager cluster for failover, updating it to three nodes is recommended. This is because of a limitation of Elasticsearch, a search and analytics engine embedded in the VMware Identity Manager appliance. You may continue to use two nodes but you should be aware of a few limitations related to Elasticsearch. See "Configuring Failure and Redundancy" in Installing and Configuring VMware Identity Manager for more information.

In the administration console, click the arrow on the Catalog tab and select Settings.
Select New End User Portal UI in the left pane and click Enable New Portal UI.
Transport Layer Security (TLS) protocol 1.0 is disabled by default in VMware Identity Manager 2.8. TLS 1.1 and 1.2 are supported.
External product issues are known to occur when TLS 1.0 is disabled. Updating your other product configurations to use TLS 1.1 or 1.2 is recommended. However, if your version of products such as Horizon, Horizon Air, Citrix, or load balancers have a dependence on TLS 1.0, you can enable TLS 1.0 in VMware Identity Manager by following the instructions in Knowledge Base article 2144805.
