Can i safely delete MSSQL Server 2008 R2 after installing 2012?

I just upgraded my MS SQL Server 2008 R2 to 2012 on my local machine. Its
all ok and there is no problems. All is working good (I mostly develop
asp.net mvc applications and some desktop applications. All of them are
pretty simple). Can i safely delete 2008 server from my computer? Are
there any things that i should care about? Thank you.
