Grafana upgrade from 6.0.1 to V7 on RHEL

Hi, Looking to up upgrade from 6.0.1 to 7.0, can that be done in one step or do we need to apply previous versions first?
Can I confirm the steps we are planning on following:-
1.Take a full snapshot of the VM grafana is installed on, used for backout
2. Export all the dashboards to flat files
3. install grafana-7.0.1-1.x86_64.rpm
4. Update plugins : grafana-cli plugins update-all
