I have one Windows Server 2003 with 35 CAL for users in local network. There is a Microsoft domain on server (Domain Controller) and server is also a file server. I'm purchasing a new Windows Standard 2008 R2 Server. New server will be also DC and file server for those same 35 users. Do I have to by 35 CAL's for new server or not ?

You can contact Microsoft Authorised Distributors in your region and ask from them:

You can also call Microsoft and speak to the licensing team:

Here's an extract from an MSDN article about CALs here: http://blogs.msdn.com/b/mssmallbiz/archive/2007/11/06/5942350.aspx

Multiple servers in domain: Microsoft server CALs can be used to access multiple servers of the same kind throughout your domain. For instance, if you have a Windows Server 2003 Device CAL for a workstation, that Windows Server 2003 CAL gives that workstation the rights to access any Windows Server 2003 throughout the domain, not just a single Windows Server 2003.

HOWEVER:

Version numbers matter: Just like the Server products that CALs are associated with, they have version numbers. For instance, for Windows Server 2003, there is a Windows Server 2003 license and there are Windows Server 2003 CALs.

The version number of the CALs being used to access the server software must be the same or higher than the version of the Server software running. As an example, if you were to purchase a license of Windows Server 2008 to replace your Windows Server 2003 and install that in your company, your Windows Server 2003 CALs would no longer have rights to access the server running Windows Server 2008, since the 2008 version is newer than the 2003 version.

Note: You can purchase newer CALs to access older server versions. For instance, a Windows Server 2008 CAL can be used to access a Windows 2003 server since the CAL version is newer than the Server version.

Control application downtime with dependency maps

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

In other words, yes, as you are installing a HIGHER version than the CALs you have now, you need to replace all your CALs, and these will cover both servers.

clinker83: New CALs are required because the server versions are different.  The article you refer to involves two servers of the same version, and as such, servers of the same version are covered by the same CALs.

infos-split has 2003 CALs at the moment, but is installing Server 2008 R2, therefore 2008 R2 Cals are required.
