Unofficial - Veriblock Nodecore-all Migration - Upgrade

Migrate-Nodecore.ps1

<#

Veriblock Update Script
Bounty 4002.2
Veriblock Telegram KernelPanick
Managed on Github Gist source: 
https://gist.github.com/gsxryan/6da7fab06e038817a400cb09c0e6cdcf

Usage:
powershell.exe -executionpolicy bypass "./Migrate-Nodecore -oldpath 'C:\Old\Install\Folder' -newpath 'C:\New\Install\Folder'"}

Purpose:
Write a NodeCore migrations script (Windows)
Copies Nodecore wallet, popfiles, blockchain to latest version
Instead of migrating-we copy- rather than delete older sensitive data

Depends:
BITSadmin to transfer .zip file
Tested in Powershell 5.1, and emulated testing down to 3.x

Assumptions:
Assuming that format link: https://github.com/VeriBlock/nodecore-releases/releases/download/$LatestVersion/veriblock-nodecore-all-$LatestVersionCut.zip
will never change.
-release appended to latest nodecore folders
-nodecore-0* will have to be updated upon major version upgrade
