Please note:  There is no need to install a new instance of DualShield on the new machine, as this process will do this automatically!

On the existing machine

• Stop services

...

sudo tar -C /opt -czf dualshield.tar.gz dualshield

• At this stage, it is strongly recommended you check where the service scripts are located
• Run the following commandCopy service scripts

ls /etc/init.d/ | grep -i dual 

• If 'dualshield' and 'dualsql' appear in the output, then copy the SysV services scripts as follows

cp /etc/init.d/dualshield .
cp /etc/init.d/dualsql .

• If 'dualshield' and 'dualsql' do not exist under /etc/init.d then copy the following systemd service script instead

cp /usr/lib/systemd/system/dualshield.service .
cp /usr/lib/systemd/system/dualsql.service .

• Copy all files to the new machine

scp -r /path/to/dualshield-files someuser@remote.server:/somepath/

...

sudo tar -xzvf dualshield.tar.gz -C /opt/

• If Systemd (see above) Copy the following Service service script

sudo cp dualshield.service /usr/lib/systemd/system/
sudo cp dualsql.service /usr/lib/systemd/system/

• Register services

sudo systemctl enable dualshield.service
sudo systemctl enable dualsql.service

• If SysV (see above) Copy the following service script

sudo cp dualshield /etc/init.d
sudo cp dualsql /etc/init.d

• You will need to also register the SysV services

sudo update-rc.d dualsql defaults 88
sudo update-rc.d dualshield defaults 89

• Create dualshield user

sudo useradd -g dualshield -s /sbin/nologin dualshield

...

sudo echo "127.0.0.1    dualshield.fqdn.com" >> /etc/hosts
sudo echo "127.0.0.1    $(hostname)" >> /etc/hosts

...

• Start services if systemd

sudo systemctl enablestart dualshield.servicedualsql
sudo systemctl enablestart dualsql.servicedualshield

• Start services if SysV

sudo systemctl/etc/init.d/dualsql start duqlsql
sudo systemctl/etc/init.d/dualshield start dualshield
