Hi Mekala,
Please find the answer to your question here on the SAP Support Portal:

Question 4 on the FAQ:
Do I need a new license key if I update my hardware?
For SAP Business Suite products, yes, the license key is tailored to your hardware configuration. If your hardware changes, you require a new license key. Please request a new license key using the License Key application.
Thanks,
Kristen
