I have my current project structure like this.
|--daos
| |
| |--readers
And I want to move whole readers packages like this.
|--daos
|
|--dbs
|
|--readers
How can I do this safely without breaking usages using intellij?
You can right click on the package and choose Refactor, then move your package from there. It will confirm what you want to do, and make the necessary changes for you.
