IDES on R/3 4.C SR2

Hi,

We have a server with :

W2K / MSSQL 2000 / SAP R/3 4.6C IDES

I reinstall the server with the:

W2K3 / MSSQL 2000 / SAP R/3 4.6 SR 2

After the installation, I realize that the IDES was not included on the SR2's CD...

Now, I want to know is there any possibilities:

=>to add the IDES on my new installation from my first version R/3 4.6C CD? without reinstalling all the server?

=>or export my client (800) from the old server and import it on the new server?

Thank you very much for your assistance.
