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.

Technically the operation 'Move Entity' ran as expected less the most important part of the component in my point of view which is the data in the entities should have been kept, but was completely deleted. So, I rate this component only with 2 stars. Even there's absolutely no reference to what happens to the existing data in the entities in the scripts which should be mentioned.
