Gotta give them credit for being willing to release it at all, but that was the rawest alpha I've ever seen. There are still patches released for it daily. I love the prominently displayed Documentation link at the top that gives you a "Coming Soon" popup.
This app brings some needed cross-cluster migration features, but at this time its so shady as to be unusable. Really. Like if you want to use it, you have to patch the hosts on both side, to match whatever level the PDM is at, and there's no patch level compatibility chart to guide you in that process.
Honestly, I just asked the devs and other forum users for the latest directions in order to get it running, and if you want to try it, that's what you should do too. Because there are no directions. Because this will all change in a week anyway.
