Removing First Exchange 2010 Database

I Installed Exchange on my lab and wanted to do some testing for HA and DR in Exchange 2010. When first exchange 2010 Server by default it will create one Database by default.

Figure 1. First Exchange 2010 Database

Before I start my testing wanted to make sure that I have all the database created in the right location with the right name. Then I created a new Database on the exchange Server and moved all the mailboxes from the default first database to the newly created database and then I tried to delete the Default first database , immediately I got the below error. Figure 2.
