Adding query string to 301 redirects

Our use case is following:

Publish an article with headline "My great article".
We have advertisement pointing to this article with an additional query string for tracking:
http://domain.com/My-great-artcile?cmpid=123

No we rename the headline to "My great article with video".
At this point we lose all tracking because of the redirect in ezp from:
http://domain.com/My-great-artcile?cmpid=123
to
http://domain.com/My-great-artcile-with-video

Are there any downsides to adding the query string to 301 redirects in ezp?
