I've downloaded the whole blockchain now I want to run a pruned node on another device. But if I klick on prune block storage in bitcoin core, it tells me that reverting this setting requres re-downloadin the entire blockchain. Is it possible to prune a copy of the blockchain I've already downloaded and if so how do I do that?

Thanks

    Pruning doesn't require downloading again. It's if you'd want to go back to unpruned state that it needs to download things again (obviously, because the data isn't there anymore). Jun 29 at 18:38
  • Ok but then how do I do that? As mentioned I can't figure out how to do it in the bitcoin core GUI. Is there a command for bitcoind that I need to use?

  • That sounds like you're already pruned, and you're trying to revert to unpruned state. Going from unpruned to pruned should just work. Jun 30 at 3:42
  • No it wasn't. Turns out the warning I got in the GUI was misleading. Upon restart it didn't re-download but just pruned the blockchain I had already stored. Thx for your time!
