How to combine different versions of Application and Firmware Software during continuous deployment

User_X72YE

In my company we have complex software product (combination of firmware software and application software) which we require to deploy continuously to our customer site(System/hardware).

Before deploying we need to match suitable version of firmware software with suitable version of application software.

Right now, we are doing it manually using a matching table.

Consider that we have 100 versions of firmware software and similarly 100 versions of application software and we need to pick suitable versions of firmware and application software on the basis of requirement of customer (which changes frequently) and deployit on his system automatically. 

Can you please inform me how can I achieve it automatically? Is there any tool available for it. or how can I achieve it more efficiently.

Kindly inform me if you need any other information.

Thanks a lot !!
