Hi all.

I was show jenkins update available LTS 1.532.1 ready message.
so, backup installed jenkins whole folder,
and try update 1.532.1(LTS) to update-center.
After jenkins update complete, restart jenkins server and check.
but, init all configuration and all jobs deleted!

so, i restored jenkins using backup files.
and download war file, backup old war file, replace downloaded file.
start jenkins server. As before initializing it.

i haven't show this results before updates.

I would like to know why it looks like this problem.

thanks.
