Update Visual Studio 2017 from Visual Studio 2015.3 and 2017 rc

Question

Good morning, I have installed in my PC (Windows 10) Visual Studio 2015.3 and Visual Studio 2017 RC, both of them with a lot of things installed on. Now, that Visual Studio 2017 is finally out, I want to have only and don't have Visual Studio 2017 RC or the "old" Visual Studio 2015. I search over internet and I find how to have an off-line installation of Visual Studio 2017. Now I don't know which is the best solution between:

1. Uninstall All plugin like resharper or so on, restart, uninstall Visual Studio 2017 RC, Restart, Uninstall Visual Studio 2015.3, restart, install Visual Studio 2017, install all plugin
2. Install Visual Studio 2017, update all plugin, uninstall Visual Studio 2017 rc, uninstall Visual Studio 2015.3

Or other...is there someone that have a simil issue?

Thanks

VS 2015:
You don't have to uninstall VS 2015, and if you want to uninstall it, you can do it later, because it is completely independent from VS 2017.

VS 2017 RC:
Additionally to the update, of course it is possible to do a fresh install. This is what I would do at least for my main development system. Updates can be more error-prone than new installations (Consider this for example): Can't update Visual Studio 2017 RC

If you prefer a fresh install I would take your sequence 1 (but let VS 2015, at least until VS 2017 was successful installed).

Edit: Just install the current version of Resharper instead of using old versions. Resharper for VS 2017 was not released the same day as VS 2017 itself, but some weeks later.
