We have a licensed Windows server 2000 and SQL server 2005. It's been working for 7 years now and we've been using an application to access the database. Any client computer (without CAL) with the application can access the server and can connect.
As we are now planing to have a second server as backup (licensed Windows server 2012 r2 and SQL server 2014) to support the primary server we have, it is possible not to purchase CAL for the clients? Since we will be using a newer version of Windows OS server and SQL server, will we have a problem when connecting to the server? As I have read, client computers without CAL will have a problem accessing the servers, that true?
