Hi All,

currently we have ISR4k router with 400 mbps internet circuit which connected to 1 gig port. we are planning to upgrade the internet circuit to 1 gig, do we need to upgrade port capacity also or not required?

I think the instruction is clear enough:  Post the complete output to the command "sh license".

If you have a 4451 or 4461 with a performance license, you're fine.

Anything less doesn't guarantee 2 Gbps but often you may not need that guarantee or your traffic mix and device configuration and a boost license may provide the capacity needed.  (The latter can sometimes be estimated by taking the CPU load percentage to your current throughput and scaling it.)
