Fully configured system on SD Card. Howto Copy?

I have a fully configured system on SD Card No1. Unfortunately this SD Card does not boot anymore ! But I can read the card in my PC. I have access to all files.

Now I have installed openhabian in SD Card No2. How can I copy all configuration files from SD Card No1 to SD Card No2 ?

I just want the configuration to be copied !

Thanky for your help !
