We have only turned it on in our TEST system so far and have not done too much actual testing with it (our sales manager doesn't like it)... but below is a very brief overview of the steps we took to turn it on (we were testing both CRM and Case management at the same time so these are for both) - may be missing a few as it was several months ago...
-activated CRM licenses in tecst database
-log into Epicor, change the company name. Log out, Lob back in and change it back -> (This is to make the configuration options for CRM available)
-Set-up CRM master tables that did not already exist: Sales Region, Sales Territory, Task Type, Task, Task Sets, Task Milestones, Reason Codes for win/loss, marketing campaign
-Configure CRM and Case Management Modules in company congi maintenance
-run CRM conversion 6880Â from server admin tools
-create updateable dashboard to add correct territory to each customer
-create updateable dashboard to close out tasks on old quotes that were closed but not "ordered"
*I also downloaded a document from epicweb called "CRM install" which helped with the explanation of this module and the steps needed
