Card not found

[akshaykulkarni1205]

I am trying to modify the chaincode to build a self project. With some research, to upgrade the chaincode and deploy it to the network a command is to be used:

composer network upgrade -c card name.

However when I try this command, with card name as peeradmin, I get the response:

Error: Card not found: peeradmin.

Can some one please help.

Thanks
