Lightstep releases new versions of Satellites to bring better performance and features to the span collection process. Always use the most recent version of the Satellite available. You can find the details of new versions in the Satellite Release Notes. Upgrade your Satellites according to the schedule provided in your contract.
To upgrade, we recommend a draining/spin-up period of the same length of time as your average recall window and a rolling upgrade. You can find your average recall window on the Reporting Status Dashboard.
