Thanks Kurt for your reply, I am new to SAS but I have been working as a SAP BO Administrator(Linux/Windows) since 14 years so I am thinking the concept of SAS would be similar to SAP BI/BO. However I need some key information that should be taken care before I actually start with our SAS upgrade. I have recently upgraded my SAP BI environment where I have used the same approach by installing the new System on new Servers and then Migrating the File Repository + System database (CMS) and later configured all the required configuration. I am exploring through the documentation available online on SAS portal as in below mentioned link. https://documentation.sas.com/?docsetId=biig&docsetTarget=n06fixagb4ezikn1mcfew8mwq8o1.htm&docsetVersion=9.4&locale=en I will upgrade our Dev environment first followed with the other, hence I have a bit scope to explore and test. It will be helpful for me if you let me know the better approach like which server needed to be installed first Metadata server, Application server or web server. Thanks in Advance for all you help. Regards, Yogesh Pande
