#pause/stop the vm
openstack server suspend cmsjenkins02


#take the volume snapshot that contains jenkins home
openstack snapshot create --name jenkins-snap <current_jenkins_volume>

#create the volume from snapshot
openstack volume create --snapshot <snap-id> newjenkins01v

#attach the volume to new vm
openstack server add volume --device /dev/vdb <new_jenkins_server> <volume-id>

#mount the volume and symlink jenkins home
mount /dev/vdb /build
ln -s /build /var/lib/jenkins

# go to jenkins page and enable localcli for admin work temporarily
#suspend all the jobs
# upgrade all the plugins
# resume all the jobs

#issues
  - use older jenkins-cli to avoid auth issues for jenkins-cli
  - look at in-process-aproval script to enable groovy execution in jobs
