A noun and verb pair came to mind that might work with this: ***Inaugurate, Inauguration***.

From [Oxford Dictionaries][1]:

> **inauguration**  
> *noun*  
> *mass noun*  
>
> 1. The beginning or introduction of a system, policy, or period.  
> *the inauguration of an independent prosecution service*
>
>  1.1 The formal admission of someone to office.  
>  *the President's inauguration*
>
>  1.2 *count noun* A ceremony to mark the beginning or introduction of something.  
> *the inauguration of the Modern Art Museum*

See 1.1: *The formal admission of someone to office*. This may also work in cases where the "admission" is imposed, though technically informal, due to the meaning in 1: *The beginning or introduction of a system, policy, or period.*
