Should we install Cidiscape if we are already using ReadyGo?

Cidiscape is not required if ReadyGO is installed, as ReadyGO has the same reporting functionality available in Cidiscape.

While ReadyGO and Cidiscape have the same user interface, ReadyGO is more robust than Cidiscape. Cidiscape provides data about the usage of and activity within DesignPLUS, UDOIT, and TidyUP. ReadyGO has the same reporting features as Cidiscape and includes additional features and tools that are not part of Cidiscape. 

Can we have ReadyGO and Cidiscape installed simultaneously?

Some institutions decide to install both ReadyGO and Cidiscape in their Canvas instance for different reporting purposes. However, ReadyGO contains all of the data and information available in Cidiscape.

If both tools are installed in your Canvas instance, they share the same People, Batches, Teams, Quick Views, and Task Runner.
