Hey, and welcome!
Well, if you install some mods now, you won't have to remove them before you upgrade, but they will most likely get lost in the process. It really depends on how many changes to the files there are in 6.2.
If you're lucky, there won't be many changes, and then you could just use
Beyond Compare to upgrade easily. However, I don't see that happening, because many new features are planned for 6.2.
