We've just purchased 20 licenses for 20 new servers. The licenses came with 2003 R2 cds. We used the R2 cds to build the new servers.
With our existing 2003 SP2 servers that do not have R2, how do I upgrade those to R2? I put one of the R2 cds in and it is asking for a key. I tried the key that came with the R2 licenses and I tried the key that was used when the server was first built a few years ago. None of them worked. Do I have to purchase and upgrade CD to get a few of our original servers upgraded to R2?
I know about upgrading the schema. That part I can handle. I just need to know how do I upgrade some of our original servers to R2?
