Porting Project from 4.26 to latest

Hi folks,

How big of a hurdle is it to port a project from 4.26.2 to the latest UE version?
Which aspect might be the most difficult? Any other tips?
Some of the assets have are not available for 5.xx so I wonder if this poses any issue?
I’d appreciate if someone could also share their personal experiences.

The game project is at good general stage with most of the gameplay features done. Graphics and soundwise still a lot to do. Menus (Menu System Pro) and Save (Rama’s) are also in place.

Your input is much appreciated, thanks!

Edit:
After moving a cloned project to 5.2, not looking good. Menus and Rama’s save system are not supported and neither is a vast majority of the most relevant Actors. Has anyone had better luck with gradually upgrading the project (to 4.9, 5, 5.2 or something) or other advice? As it is, its closer to starting the project from scratch.

Best thing to do is just make a copy and open it in 5.

I don’t think you’ll have many problems, but it’s really hard to say anything about specifics.
