Copying QAD Backend Programs on the Application Server
Follow the instructions in the sectionCopying QAD Backend Programs on the Application Server with the following notes:
QADCRMInstallDir refers to the newly installed CRM 6.7 folders on your Windows Deployment server.
Since you already have a CRM 6.6.3 system integrated with QAD EA, make sure that you create a folder under QADERPInstallDir/qadcrm/<New CRM6.7 env name> for CRM 6.7 program files that need to be stored in the backend Application Server; for example, QADERPInstallDir/qadcrm/qad67test.
If your CRM Progress AppServer machine is not using OE11.x (32 bit) or OE10.2Bxx (32 bit), copy the back-end program source files from the Windows Deployment server to the AppServer machine and recompile them against your newly converted CRM 6.7 database. In this scenario, follow all instructions related to the configuration of a Progress 64-bit AppServer in Copying QAD Backend Programs on the Application Server and Compiling QAD CRM Backend Programs on the Application Server.
