then a warning will be raised in the {project_name} logs.
or Keycloak CR as outlined in the blueprints. All `remote-store` configurations must be removed from the cache configuration file.
. Review your current cache configurations in the external {jdgserver_name} and update them with those outlined in the latest version of the {project_name}'s documentation.
. While previous LoadBalancer configurations will continue to work with {project_name}, consider upgrading
an existing Route53 configurations to avoid prolonged failover times due to client side DNS caching.
= Deprecating remote-store in embedded Infinispan caches
In {project_name} versions 24 to 25 to achieve a multi-site setup, a remote store in embedded Infinispan caches was configured.
Manual configurations for the cache XML for multi-site were discouraged as CLI options to configure the caches are available.
With the upgraded multi-site feature in 26, the same CLI options exist, but don't use embedded Infinispan caches anymore.
In the community, remote stores for embedded Infinispan caches were used in some setups to keep user sessions when the {project_name} cluster was shut down or upgraded.
This was never supported, documented or tested.
As a fully supported alternative, the persistent user sessions feature should be used instead.
Due to this, using remote caches in embedded Infinispan caches is now marked as deprecated with the plan to remove it.
As it was never used outside multi-site setups that now achieve this by different means, it might be removed even in a future minor release.
To be able to use the deprecated feature, you need to enable the feature `remote-store-cross-dc` or {project_name} will not start.
There is an experimental feature `remote-cache` which allows leveraging the new multi-site mechanisms to store session related data in an external {jdgserver_name} server also for single site setups.
= Admin Bootstrapping and Recovery
It used to be difficult to regain access to a {project_name} instance when all admin users were locked out. The process required multiple advanced steps, including direct database access and manual changes. In an effort to improve the user experience, {project_name} now provides multiple ways to bootstrap a new admin account, which can be used to recover from such situations.
