To upgrade Harvest

Stop harvest

cd <existing harvest directory>
bin/harvest stop

Verify that all pollers have stopped:

bin/harvest status
pgrep --full '\-\-poller'  # should return nothing if all pollers are stopped

Follow the installation instructions to download and install Harvest and then copy your old harvest.yml into the new install directory like so:

cp /path/to/old/harvest/harvest.yml /path/to/new/harvest.yml

After upgrade, re-import all dashboards (either bin/harvest grafana import cli or via the Grafana UI) to get any new enhancements in dashboards.
