[GNC] Updating from v 2.6.16.

[Mike Stillingfleet]

Good Evening All,

It would appear that my current version of 2.6.16 is a bit out of date.

I have been looking at a route to updating. 

I see that I can download a stable version 3.11 and 4.8.

My question is can I install all 3 versions at the same time so that I can migrate and check the integrity before moving forward whilst ensuring that I still have a viable system in 2.6.16.

If so how would I do the install.  I use Windows 10.

T.i.a
