Integrating with QAD EE
To integrate CRM 6.6.2 with your QAD EE system, implement the steps in the following sections:
Integrating QAD CRM with QAD EE
Configuring the Environment for Sales Order Integration
Go to QXtend Inbound and update the Connection Pool ee-crm.SIAPI to use the CRM 6.6.2 AppServer. It is unnecessary to reimplement all the steps in Configuring QXtend for Integration.
Note:  
QADCRMInstallDir refers to the newly installed CRM 6.6.2 folders on your Windows Deployment server.
When you define PROPATH in configuration files, make sure that you refer to the correct QADERPInstallDir/qadcrm/<New CRM6.6.2 env name> folder that you created earlier in Copying QAD Backend Programs on the Application Server.
Ensure that you update the PROPATH of all configuration files that are used to reference the old CRM 6.6.1 programs. The PROPATH include the PROPATH setting used by the .NET Connection Manager pool startup script, the PROPATH setting defined in the Progress ubroker.properties file for the QADUI AppServer, and etc. Update of the PROPATH ensures that all elements point to the new CRM 6.6.2 programs that you have installed.
