[SERVER CRASHED] Restore CWP from files ?

My old centos server recently ran into some problem. I was able to backup every files from it though. I now have a new server and all the old files in a folder. How do I go about restoring it to old state ? As in I want to restore all users, websites, databases ,etc

I have tried :-

-copy pasting important directory which was a terrible idea
-Installing cwp and tried copy-pasting users, mysql files, /home files and old cwp config

It wouldn't work. Cwp's user panel shows MYSQL DB 0/10 although pma shows databases. Everything is messed up. Is there a clean way to restore it?

Help would be much appreciated
