Because when I saw and understood the time that will take the transfers (BTC rsync umbrel -> local & local -> Start9; a lot), I wanted to compare the BTC sync time between Umbrel and Start9. Right now, pretty much the same 😅
Discussion
Is it not the same machine?
It its the same but I followed this tutorial and they say flash Start9 on a new SD card so I did the same. But yes it's a better solution to reuse the BTC data instead of redownloading its again from scratch... maybe I'll finaly do it if I test MyNode or Raspiblitz 😅
If yes, you just needed to copy the data folder in bitcoin app in umbrel to wherever in start9
