SSL key Apache

We are running Apache 1.3 on solaris 8 we have renewed our ssl key with verisign. They have confirmed renewel and new ssl certifcate is appended to the end of the email.
out apache config file has two directives
SSLCertificateFile /export/home/apache/conf/ssl.crt/xxxx.crt
SSLCertificationKeyFile /export/home/apache/conf/ssl.key/xxx.com.key

Can anyone please advise in which file I have to cut and paste the new certifcate
Are there any additional steps involved.

Thanks

Verisign cert install instructions

Paste the key that was appended via email into a xyz.crt
Use the .key file that you used to gen the particular CSR to verisign

thanks for your assistance
