+ Known Limitations, Issues and Workarounds
+ -----------------------------------------
+
+ *System Limitations*
+
+ For upgrading, CPS uses Liquibase for database upgrades. In order to enable Hibernate write batching
+ (`CPS-1795 <https://jira.onap.org/browse/CPS-1795>`_), a change to the database entity ID generation is required.
+ As such, *this release does not fully support In-Service Software Upgrade* - CPS will not store new DataNodes and
+ NCMP will not register new CM-handles during an upgrade with old and new versions of CPS running concurrently.
+ Other operations (read, update, delete) are not impacted.
