Upgrading Cisco Access Registrar Software
CAR 4.2 supports software upgrades from your previously installed Cisco AR software while preserving
your existing configuration database. Cisco AR supports an upgrade path for both the Solaris or Linux
versions of Cisco AR software.
Note Configuration for Prepaid billing servers in Cisco AR 3.0 will no longer work in CAR 4.2. If you have
been using a Prepaid billing server in Cisco AR 3.0 and are upgrading your software to CAR 4.2, you
must remove the Prepaid billing server configuration before installing the CAR 4.2 software.
Chapter 15,
“Using Prepaid Billing,” provides detailed instructions for configuring Prepaid billing services for
CAR 4.2.
Caution Running the command mcdadmin -coi to import configuration data will cause the CAR 4.2 server to
lose all session information.
