Upgrade 32 bit version to 64 bit version on windows server 2003 enterprice

Not possible, you need a new clean format from 32 to 64 systems.

no possibility here. You will need to start from scratch. The reason is that there are many modules in 64 bit which need to be reinstalled and linked to the hardware structure.
Why do you want to do that.

If you are going to do it why not upgrade to newer version of server.

if RAM can be extended to 32 GB in 32 bit OS i dont have to upgrade, just need to upgrade RAM from 4gb to 32 GB

Kindly advice.

32 systems can only see up to 4 GB RAM...

unfortunately the only option that you have is a clean installation.

No that is not true.  You need to enable PAE to see beyond 4 Gig.

But if you want to install a 64-bit OS, then you will need to do a clean install.  No upgrade path from 32-bit to 64-bit.

Yes, 4 GB RAM is the limitation of std. Edition not 32 bit systems.

The author is NOT running the Standard Edition, he is running the Enterprise version.
