Level Number to Level Name

I am wanting to take a few (1000) DGNS and change the level numbers and to actually logic name. 

I am wanting to do it by color and level number

example: level 24 color 2 to a "new" level named STRUCTURE 

level 24 color 0 to a "new" level named NEW STRUCTURE

Does anyone have any tips for doing this to multiple files at once?
