the only method is to select all files and migrate in a project versione 4.10 or exist another method to do this?
Once you have 4.10 installed, open it and the Project Browser will open. From here, you can browse to the project you want to convert. Select and open it, and it will ask you if you want to make a copy in 4.10. This will create a copy and convert it to 4.10 automatically.
Another method, if you don’t want to make a copy, is to either Convert in Place or right click the .uproject file for the project and select 4.10 to open it. These are not recommended, however, as it will not make a copy of the project and if there are any problems with the conversion, you won’t have a backup and could lose your entire project.
Hope that helps!
