The RunId
The CLI leave a breadcrumb in each created object/version in EP V2 in the form of a custom attribute:
ep-migrate-run-id={runId}
A new runId is generated for every run and is based on the formatted timestamp:
YYYY_MM_DD_HH_MM_SS_MMM, e.g. 2023_05_25_10_26_40_290
This allows you to search for the runId (or the partial runId) in the catalog to see all the objects / versions that were created as part of a run.
