Well since they are the exact same server you dont need to worry about compatibility.

Once the second CPU is connected the system should automatically pick it up.

Christophermagee is correct about the compatibility, as long as they ARE the same (or similar enough) systems.

If they are the same (let us know if you aren't sure) be sure you thorougly clean the CPU to be moved and the CPU heat sink. ArctiClean by Arctic Silver (http://www.arcticsilver.com/arcticlean.htm) is absolutely incredible when it comes to removing old thermal material, even pads. Then be sure to use some form of thermal paste or grease on the new CPU. Otherwise you may fry your processor.

On the hardware side, running two cpus in dual configuration requires matched cpus, typically down to the stepping of the cpus.

If the OS was not installed with a multiprocessor ACPI driver, you will need to update it in order to make use of both cpus.  You may not be able to do this easily - see http://www.experts-exchange.com/Operating_Systems/WinXP/Q_21809283.html, but a repair install may accomplish it.
Will You Be GDPR Compliant by 5/28/2018?

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

Wait a minute... are you talking about replacing/upgrading a processor or ADDING one? Callandor and I are on a different page here... let us know.

Yes, Callandor's right - if you had ONLY one CPU and you want to add another one to make it be a DUAL CPU server - you'll need to upgrade your OS to multiprocessor kernel, it IS possible without reinstalling the system, I personally tried it on my Dual P3-866
