Unable to Rename the module Atlas_UI_Resources to Atlas_Core during version upgrade.

Hi all,   Am currently upgrading my application from 8 to 9.6.10 version. Am in a process of upgrading the UI following the document Migrate From Atlas 2 To Atlas 3 | Mendix Documentation When i try to rename the module Atlas_UI_Resource to Atlas_Core for upgrading it is giving me the following error message.   Please advice did i have to rename the javasource file also or what should i do.

You should be able to just remove the atlas_core directory from your application’s javasource directory. 

Good luck!
