Replacing Desktop Authority with Group Policy

As some of you may or may not know I spent a large amount of time at my last company completely redoing Group Policy/Active Directory configurations.

Well as of two weeks ago I started a new job (60% more money, twice as much time off, 10 less hours of work a week, and a better corporate culture). The new company currently uses Desktop Authority as a supplement to Group Policy but many of the configurations used can just be applied through GP.

 I prefer using GP for as much as I can especially in 2008R2+ domains, as such I plan on presenting a plan to slowly convert from GP + DA to completely using GP for our systems configurations.

Anyone who has done this, anything I should look out for or any reasons to not go ahead with this conversion?
