17.5. Migration of access scopes to collections

Database changes in RHACS from rocksdb to PostgreSQL are provided as a Technology Preview beginning with release 3.74 and are generally available in release 4.0. When the database is migrated from rocksdb to PostgreSQL, existing access scopes used in vulnerability reporting are migrated to collections. You can verify that the migration resulted in the correct configuration for your existing reports by navigating to Vulnerability Management Reporting and viewing the report information.

The migration process creates collection objects for access scopes that were used in report configurations. RHACS generates two or more collections for a single access scope, depending on the complexity of the access scope. The generated collections for a given access scope include the following types:

For access scopes that define cluster or namespace label selectors, RHACS can only migrate those scopes that have the 'IN' operator between the key and values. Access scopes with label selectors that were created by using the RHACS portal used the 'IN' operator by default. Migration of scopes that used the 'NOT_IN', 'EXISTS' and 'NOT_EXISTS' operators is not supported. If a collection cannot be created for an access scope, log messages are created during the migration. Log messages have the following format:

Failed to create collections for scope _scope-name_: Unsupported operator NOT_IN in scope's label selectors. Only operator 'IN' is supported.
The scope is attached to the following report configurations: [list of report configs]; Please manually create an equivalent collection and edit the listed report configurations to use this collection. Note that reports will not function correctly until a collection is attached.

You can also click the report in Vulnerability Management Reporting to view the report information page. This page contains a message if a report needs a collection attached to it.
