Coexistence with OpenSSO Enterprise 8.0

Coexistence can occur when instances of OpenSSO Enterprise and Access Manager 7.1 access the same Directory Server schema. (In previous versions of Access Manager, the Directory Server schema contains the server's configuration data.) Thus, OpenSSO Enterprise 8.0 can coexist with an instance of Access Manager 7.1 only if the older version was installed with the Directory Server schema. Coexistence mode denotes that customer has executed the ssopreupgrade script to remove the packages but not the ssoupgrade script to update the schema.

Coexistence usually occurs when multiple instances of Access Manager 7.1, accessing the same Directory Server schema, are being upgraded sequentially, one instance at a time. OpenSSO Enterprise 8.0 will continue to work with the Access Manager 7.1 schema and support all Access Manager 7.1 features (except for the Liberty ID-FF metadata as described in Backward Compatibility with OpenSSO Enterprise 8.0) until the schema is upgraded.

Important. In coexistence mode, all Access Manager 7.1 instances accessing the same Directory Server schema must have the same deployment URI (for example /amserver).

Coexistence is not supported between OpenSSO Enterprise 8.0 server and these releases:

• Access Manager 7 2005Q4

• Federation Manager 7.0

More information about upgrading multiple instances of Access Manager is in Upgrading Multiple Instances of Access Manager.

Upgrading from older versions of Access Manager might cause issues when logging in and accessing realms in coexistence mode. There is no current workaround for this issue. It is suggested that you upgrade to OpenSSO Enterprise 8.0 update 1 once it is available.
