Hello, I am using the LTS version (1.424.2). When I click on manage jenkins, I see a warning saying "You have data stored in an older format and/or unreadable data." with two buttons "manage" and "dismiss". Last time I saw this on non-LTS version of jenkins, and I clicked dismiss, and I experienced some problems (which can be related to this or something else because I was also changing other things)
My question is what is the reason for this warning, and how should I proceed ? Mete
