Can I upgrade 5.3 project to 5.4?

Yes, as far as I know you can change engine version for you project.

Go to the main folder of your project and press with the right mouse button on you "Game.cryproject" file. Then select "switch engine" and choose 5.4 on the drop down.

Hope that helps

Look over your flowgraph charts. Most likely some flownodes have been removed between 5.3 to 5.4. Most likely it will be labeled MISSiNG in red text.

You can upgrade to 5.4 but be aware that the binary DLL file will have to be rebuilt.
Also see the migration notes located on our docs pages.
