Overview

You can upgrade CA IDMS to Version 18.0 from previous releases 10.x, 12.0, 14.0, 14.1, 15.0, 16.0 or 17.0. The Version 18.0 installation delivers the conversion utilities that you need to upgrade from all releases except from release r10.x.

This Release Notes guide describe the actions required to upgrade from r17 to Version 18.0. If you upgrade CA IDMS to Version Version 18.0 from a release previous to r17, review all the intervening CA IDMS Release Notes documents for the cumulative requirements for your upgrade.
