Use the ACRU Lite tool to update a SecureAuth IdP Appliance to use the redundant SecureAuth Cloud environment. The tool installs all applicable certificates, updates cloud communication URLs, and updates InterCert values in web.config files.

ACRU Lite can only be used on SecureAuth IdP versions 8.1+. For pre-8.1 appliances, the machine(s) must be updated to SHA 2 (via ACRU) and then updated to a post-8.1 version before ACRU Lite can be run on the appliance(s). Contact SecureAuth Support to schedule an upgrade.


1. Have a SecureAuth IdP Appliance on version 8.1.0 or greater

2. Have customer approval for downtime to be incurred during the ACRU Lite process

3. Ensure all applicable firewalls allow traffic to these ports
