we setup three store Store View Name's a long time ago when this should have been Store Name's. 

We are now busy rolling out multi language and this is where I discovered the mistake. 

Is there an easy way (and how) to move a Store View Name to a Store Name (1 up in hierarchy)

    www.domain.com	domain.com	store1_NL
    www.domain.com	domain.com	store2_NL

becomes 

    www.domain.com	store1		NL	
    www.domain.com	store2		NL
    ...
    www.domain.com	store2		EN
    www.domain.com	store2		DE
    etc

Thx!!
