Can anyone help with getting this replay from replay.gg to work on the new client?

I played my final game of pre-rework Katarina and I wanted to go and see if the file still worked on the new client... Turns out, it doesn't. It was a perfect final game of my main with a pentakill and my old-fashioned build, and I'd like to keep it if at all possible. If you can help, please do, as I have no idea how to fix it. My assumption is to change the directory, but I'm not even sure what I'd have to change it to and from.

The replay.gg was the following:

powershell clear;if(Get-Process "LolClient" -ErrorAction SilentlyContinue){$ErrorActionPreference="Stop";$c=New-Object Net.Sockets.TcpClient;$c.Connect("127.0.0.1",8393);$c.GetStream().write((16,0,0,0,1,0,0,0,0,0,0,0,69,0,0,0,114,101,112,108,97,121,32,114,101,112,108,97,121,46,103,103,58,56,48,56,48,32,57,70,56,97,47,87,77,43,105,99,43,107,122,98,85,110,114,52,115,53,118,55,87,121,79,49,99,97,76,56,112,103,32,50,51,52,49,48,54,53,55,49,52,32,78,65,49),0,85);Exit;}"Error.
