Installing QAD CRM 6.6.2 on the Deployment Server
Install QAD CRM 6.6.2 from the installation CD. For the installation instructions, see Installing QAD CRM on the Deployment Server.
Note:  
When you prompted to remove the existing CRM 6.6.1, answer No. You have the option of removing the CRM 6.6.1 configuration later after you have confirmed that the CRM 6.6.2 configuration is working correctly.
You do not need to follow the instructions in Setting Up the Database Server in this CRM Installation Guide, since now you are converting the existing CRM 6.6.1 to CRM6.6.2.
