Based on the fact that Microsoft will be stopping the support for Windows 2003 servers, we are helping one of our client to migrate all the existing applications from Windows 2003 server to Windows server 2012 R2.
In the process, we have witnessed some of the legacy applications are having compatibility issues and need some remediation which we don't think we will be able to complete by July 14th 2015. so, If our client needs extended support from Microsoft for Windows 2003 servers, what will be the Premium charge that Microsoft will be charging the customer per server per annum ?
Thanks in advance.
