How to install/update the Upgrader tool on Windows 10

Silverstripe Version:

I’m trying to upgrade my old Silverstripe project following the guide at using the upgrader tool.

I’m trying to follow the steps below but these commands don’t work on Windows 10. How am I able to update/install the upgrader tool?

I have composer installed and if I enter upgrade-code --version in my command line it returns SilverStripe Upgrader 1.0.0

I’m also new to Windows and Silverstripe.

To install the PHAR executable:
1. Download the upgrader as a PHAR executable or wget
2. Make the file executable chmod +x upgrade-code.phar
3. Move the file to a folder in your path, for example sudo mv upgrade-code.phar /usr/local/bin/upgrade-code
