Upgrade is not supported for an Access Manager 7.x Distributed Authentication UI server deployment. To move from an Access Manager 7.x deployment, you must remove the old deployment and then install the OpenSSO Enterprise 8.0 version, as described in Chapter 9, Deploying a Distributed Authentication UI Server, in Sun OpenSSO Enterprise 8.0 Installation and Configuration Guide.
OpenSSO Enterprise 8.0 can coexist with an Access Manager 7.1 Distributed Authentication UI server deployment. However, make sure that the following properties in the AMConfig.properties file on the Distributed Authentication UI server side in the WEB-INF directory are in sync with the OpenSSO Enterprise 8.0 server instance:
com.iplanet.am.naming.url
com.iplanet.am.server.protocol
com.iplanet.am.server.host
com.iplanet.am.server.port
com.sun.identity.agents.app.username
com.iplanet.am.service.password
Note: If you make any changes to the AMconfig.properties file, you must restart the Distributed Authentication UI server.
