We\'ve been using Grails for a little while now and have been through a few Grails versions now. We don\'t always want to migrate our \'older\' apps immediately but often us
It's now MUCH much later, and GVM is not the tool it once was. Instead, I use SDKMAN (https://sdkman.io/) and, with Windows getting some linux-like tooling, or using Cygwin, etc. it's installable on Windows.

GVM is a tool for unix/mac environments to manage Groovy/Gradle/Grails/more versions, and someone finally made a Windows equivalent called Posh-gvm (short for Power-shell GVM). It's very useful and easy to use to download and configure your environment for whichever version of these tools you want to use at any point in time.
If you're using an IDE, posh-gvm is still a great way to download/install the new versions as they come out, and your IDE can point into the posh-gvm install directories.
