The following are instructions for upgrading Bitseed v1 to Bitcoin Core 0.11.0 (or current latest verified version).
Information about changes and features in Bitcoin Core 0.11.0 are summarized here. Pruning is supported, but not enabled by default.
The instructions add an upgrade script to the device. It will delete your old binaries and replace them with the latest binary files built by Bitseed. The script will stop bitcoind and then restart it when done. All blockchain data and settings will remain unchanged.
ssh into the device (windows can use putty)
password: (printed on bottom of device)
wget -4 https://bitseed.org/device/latestversion/bitcoin-upgrade.sh
chmod 755 bitcoin-upgrade.sh
Bitcoin will then be restarting. Allow 15 minutes for it to verify the blockchain and start up.
The script can remain on the device and can be run at any time to get the latest version that has been built and tested by Bitseed.
