For converting .key file to .pem file,

Your keys may already be in PEM format, but just named with .crt or .key.

If they begin with -----BEGIN and you can read them in a text editor (they use base64, which is readable in ASCII, not binary format), they are in PEM format.

If the file is in binary, for the server.crt, you would use 
	openssl x509 -inform DER -outform PEM -in server.crt -out server.crt.pem

	For server.key, use openssl rsa in place of openssl x509.

I got an error while setting up an site, which is having some changes with their file names (Diff. in Upper/Lower case).

[Thu Oct 31 00:29:59 2013] [error] [client x.x.x.x] script '/var/www/www.abcd.com/wwwroot/mlbteamstandings_data.php' not found or unable to stat, referer: http://demo-abcd.xyz.com/index.php?option=com_content&view=article&id=86&Itemid=839

So, issue has been resolved by adding apache2 CheckSpelling and CheckCaseOnly module into the virtualhost file.

<VirtualHost *:80>
        ServerName demo-abcd.xyz.com
        DocumentRoot /var/www/www.abcd.com/wwwroot
        <Directory /var/www/www.abcd.com/wwwroot>
