Can someone please help me on how to upgrade Qt libraries to latest version (4.5 to 5.12)

I am working on a project and have an older version. But I am suggested to upgrade it to a newer version specifically v5.12. So could someone of you help me with the steps to upgrade the libraries to latest version?

@Chaitu247 hi ,
You can download last version with MaintenanceTool, for me its in C:\Qt
then, delete your projectName.pro.user file and open your project in QtCreator, choose the new version at kit configuration step, build

Hi @Chaitu247, and welcome!

(4.5 to 5.12)

This is quite a big change. Read through https://doc.qt.io/qt-5/portingguide.html and the links inside to get started.

@JKSH Hello thank you much for responding. Will I be able to update the libraries with this knowledge provided by you?

Hi and welcome to devnet,

Yes, you should. Usually the porting guides a pretty well written in that regard.
