Sysupgrade question for new device (TL-WPA8630P V2)

Yes and No: Yours seems to be a v1 which is already officially supported. I've git one, too, and used @netadair's build for an initial flash and did a sysupgrade afterwards. If you check [Solved] TL-WPA8630P Lede does not install they're discussing the v1 and the initial installation problems (as well as P vs. non-P)
