Copying QAD Backend Programs on the Application Server
Follow the instructions in Copying QAD Backend Programs on the Application Server with the following notes:
Since you already have a CRM 6.7.1 system integrated with QAD EA, make sure that you create a folder under QADERPInstallDir/qadcrm/<New CRM6.7.2 env name> for CRM 6.7.2 program files that need to be stored in the backend Application Server; for example, QADERPInstallDir/qadcrm/qad672test.
Copy the backend program source files from the Windows Deployment server to the AppServer machine and recompile them against your newly converted CRM 6.7.2 database.
