With changing times , CSP Model has gained more popularity across the companies currently using Azure ! Not only the Model provides great benefits , it also makes life easy for the companies IT Departments .
Customers use Azure in different models mainly Pay as you go , EA , BizSpark etc . With the entry of CSP model , it has become the most popular of all these models . The Model is a Win-win for both the customers , Microsoft and its partners .
While the customers can migrate to CSP from most of their Existing Models , but you can have hard time with EA . Moreover if you are currently on ASM , you would first need to migrate to ARM based Model and then to CSP .
I found the attached guide from MS very useful if you plan to migrate your resources to CSP Model .
