Jenkins setup: no info.

Hi all.  
So, the question is next:  
I had a VM with CentOS 7 and Jenkins. Was trying to update CentOS, but seems like it didn’t work. But also I lost old Jenkins. Now, if I’m trying to start Jenkins (type “jenkins” in terminal), I’m getting the message that it needs to be configured/etc, looks like it’s new. But I have old Jenkins data (folrder with jobs/plugins/etc). How can I recover old Jenkins ? Thank you very much
