This migration kit allows to upgrade an existing AEM 6.4/6.5 version to Felix Health Checks and also includes some additional packages for special use cases:
hc-migration-felix-healthcheck-package: Will install Felix HC bundles and re-configure the AEM UI at /libs/granite/operations/content/healthreports/healthreportlist.htmlhc-migration-legacy-systemready-endpoints-package: Will provide the endpoints /systemready and /systemalive in case you already have a k8s setup relying on those endpointshc-migration-better-startup-handling-package: Replaces the AEM ootb startup filter with the Apache Felix ServiceUnavailableFilterhc-migration-better-deployment-handling-package: Configures AEM to return reliably 503 during deployments
HINT: The packages contain official Sling/Felix bundles and configurations only to upgrade an existing AEM instance (the target environment being AEM is the reason why these packages do not reside at Apache).
