      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.

              Hi and welcome to devnet,

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

                Hi @Chaitu247,

                and to add to @SGaist, you can always ask here in case something is unclear.

                Regards

                Qt has to stay free or it will die.
