I’ve deleted a universe and I’m in a mess! What do I do now?
Keep away from sharp objects 
. Take a deep cleansing breath and don’t panic 
First, ask yourself some questions:
Can you get a copy of the universe from the web server?
Can you get a copy from another user or Designer’s PC?
Do you have a backup copy in a source control system?
Do you have a repository backup that your DBA could restore to a temporary location? If so you could do the stuff in this post and import the universe.
Reports will complain if they are unable to find the universe you’ve deleted. A thorough explanation by digpen is located here.
