Instructions for relocating the artdaq database services from one server to another within the np04 DAQ cluster.

On np04-srv-010 (the old server) run as root:

systemctl stop  webconfigeditor@cern_pddaq_v3x_db.service
systemctl stop  mongodbserver@cern_pddaq_v3x_db.service
systemctl disable  webconfigeditor@cern_pddaq_v3x_db.service
systemctl disable  mongodbserver@cern_pddaq_v3x_db.service
systemctl status  mongodbserver@cern_pddaq_v3x_db.service
systemctl status  webconfigeditor@cern_pddaq_v3x_db.service

Copy SystemD configuration files from np04-srv-010 to np04-srv-009.

scp /etc/systemd/system/*cern_pddaq_v3x_db.service root@np04-srv-009:/etc/systemd/system/

On np04-srv-009 (the new server) run as root:

systemctl enable mongodbserver@cern_pddaq_v3x_db.service
systemctl enable webconfigeditor@cern_pddaq_v3x_db.service
systemctl start  mongodbserver@cern_pddaq_v3x_db.service
systemctl start  webconfigeditor@cern_pddaq_v3x_db.service
systemctl status  mongodbserver@cern_pddaq_v3x_db.service
systemctl status  webconfigeditor@cern_pddaq_v3x_db.service

Check if statuses reported as "running" and save all console outputs into the logbook.
