Good Component!

Is used this component to move roles, and if you follow the instructions properly (with a little bit of thinking) it works perfectly fine!

I only have two comments:

1. Maybe it should be mentioned somewhere that even though the role grants are preserved, the access of the roles to screens are NOT. So after I moved the roles, I had to go by each screen of my application (which are a lot) to set this right again.

2. The last step in the instructions for moving roles is incorrect. It should be the same as the last step for moving an entity. When I simply published the whole solution to TST after moving the roles, the grants were lost. When I first published a solution to TST containing the target environments and refactor, before publishing the whole solution, the grants were preserved. 

Works fine!

Add the same issue as @Tiago Baptista, but after looking into the documentation I realized I skipped an important step:

2.c In Service Center create a solution containing <Source eSpace> and <Target eSpace> espaces and then publish the solution with full compilation

After deploying the solution with both espaces with full compilation the data was shown.
