Distributed tracing is applied during an upgrade from a first management appliance to a second management appliance. The distributed tracing method includes generating a parent span that encapsulates states of the overall workflow, including a span context that contains a trace identifier and a span identifier, and generating a plurality of child spans. Each child span encapsulates states that represent a piece of the workflow and contains a reference to the parent span context. The states of the child spans include an error tag that indicates whether the piece of the workflow associated with the child span executed with an error. Because child spans may be generated for a piece of the workflow that is executed by a service running in the first or second management appliance, the span context for the parent span is persisted by the first management appliance and replicated for use by the second management appliance.
