Upgrade OBIEE 10g to OBIEE 11g


What happens during 10g upgrade to 11g?
By default, existing users and groups migrated to embedded WLS LDAP. Existing groups are automatically mapped to an Application role.
10g catalog groups are automatically migrated in the upgraded catalog and assigned the same privileges, access, and membership.
“Administrator” user automatically added as member of “BIAdministrators” group in embedded WLS LDAP and granted Administrator role. The user specified during OBIEE 11g installation (i.e. “weblogic”, “biadmin”) is also a member of the BIAdministrators group.
Prompted to set a repository password while running the upgrade assistant. Do not lose this password as there is no feature to recover a lost password.
Upgraded RPD will continue to point to 10g LDAP or external tables. Initblocks may need to be modified to ensure that deprecated, or reserved word, variable names are renamed.
NOTE: If you intend to use another LDAP server, such as Oracle Identity Management (OID), then you must upgrade to the embedded LDAP server first, then
migrate to the production LDAP server.
Existing groups will be migrated. Recommendation is to use application roles instead. Privileges on catalog objects may be granted to an application role via BI Presentation server Administration link.
Upgraded 10g RPD will point to external tables. Initblocks may need to be modified to ensure that deprecated, or reserved word, variable names are renamed.
“Everyone” group migrated to AuthenticatedUser role.
