After OnBase 15 and its service packs, the RAC Administration module can only be upgraded to OnBase 16 SP 2. If you are using the RAC Administration module and upgrading to OnBase 16 or later, you must either continue using the RAC Administration module for OnBase 15 (in conjunction with an OnBase 15 Application Server) or upgrade to OnBase 16 SP 2. Please contact your OnBase solution provider for further information on the availability of the RAC Administration module for OnBase Foundation 22.1 or later.
