3. Removal of Masternode Private Key #

You can keep using your existing Collateral Tx, Collateral Tx Index and BLS Private Key. In this release. Masternode Private key which was generated using Masternode genkey has been retired and therefore this can be removed from your absolute.conf.

4. Your VPS Server #

Use Putty or Kitty to connect to your VPS via SSH. Make sure you have at least Ubuntu Linux v18.04 installed.

5. Upgrade Masternode using upgrade script #

This script is designed for users that have used our install script. Manually configured nodes with non-default configurations and paths can’t be upgraded with this script. If, this is the case follow the manual guide in step 5a.

This script will detect your configuration and stop daemons, download new binaries, upgrade wallet binaries, update sentinel and restart the daemons.

Make sure you are the root user, if you use a different user to login to your VPS then switch the current user to root and navigate to /root folder with this shell command:

cd /root

Download the install script with this command:

wget https://bit.ly/abs_mn_wallet_upgrade -O abs_wallet_upgrade.sh && chmod +x abs_wallet_upgrade.sh

Start the install script with the next command.

./abs_wallet_upgrade.sh

Make sure that the script run without errors!

Script will upgrade the wallet of running nodes, so no need to stop the daemons before running it.

Once complete, the upgrade is complete there is no need to continue to step 6a and 6b
