It depends on how you bought Office for the old computer.
Only one one type of MS license is transferable to new computer. It is known as a FPP license. Typically you get a FPP license by buying the Retail (big ugly ecologically insensitive, mind bending) Yellow Plastic box With the CD in it. You can also get FPP
licenses electronically, but you have to ask for them specifically and pay a little more.
Other MS licenses include:
- MLK (Medialess Key) ie electronic download,
- OEM, preinstalled by manufacturer.
- PKC, Product Key Card
These licenses are typically sold at at discount from the retail price.
You have to figure out what type of license you have.
If you have a FPP license, to transfer it, you simply uninstall it from the old machine and install it on the new machine. In theory, internet activation should be automatic, but you may have to phone activation and explain to the service rep. During install
and activation you are given option of doing internet or phone activation.
So without further investigation you could simply do the uninstall, install and see what happens. If you have to do the phone activation the SR will explain to you that the product key does not quality for transfer.

Office 365/2016
Please note that this is a VERY OLD reply originally written for Office 2010 and earlier. If you are looking for instructions on how to "transfer" or simply "install" an Office 365 license things have changed quite a bit. Office 365 "license management"
is now handled/controlled by you the user/license owner through the "MyAccount" web page. For example, to install Office 365:
- Go to the My Account page at
https://office.com/myaccount
- sign in using your Microsoft Account/Email ,
- click the install button to start the installation process.
- Depending on your browser go to the install pop up that appears and click Run (in
Internet Explorer) Setup (in Chrome) or Save File (in Firefox).
- Your install is finished when you see the phrase "You're all set! Office is installed
now" and an animation plays to show you where to find Office applications on your computer.
