Old Server housekeeping
Update your server
Run as sudo / root user
Reboot if you have a new kernel installed during the update that needs loaded.
sudo -s &&apt-get update -y && apt upgradeStop old system service
Use status to check if its running, stop to stop the service, and disable to prevent it from loading next reboot
systemctl status xand.service
systemctl disable xand.service
systemctl stop xand.serviceSSH Keys
If you want to make a new user sol to match the new guide, then make sure your ssh keys to login remotly are stored in your home dir for sol or root users (not only in xand home dir. Careful with the ssh keys...if you remove them you could lock yourself out of your server...
Check for keys in root
sudo cat ~/.ssh/authorized_keysCheck for keys in xand
su xandcd ~
cat ~/.ssh/authorized_keysCopy from xand and append to root keys file
sudo -isudo cat /home/xand/.ssh/authorized_keys >> /root/.ssh/authorized_keysValidator Keypairs
Make sure you have copied your validator keypairs if they are needed for the new server.
Otherwise they can be created new during install of the validator software.
There is no reason to re-use the old one, only personal preferance.
Remove xand user account
Once you have sucessfully logged into your server using either root or sol user, and copied/backed up any files you need, you may wish to remove everything from xand user and their files.
sudo -suserdel -rf xand
