Moved or given together with something else.
The data was cotransferred to the new system during the upgrade.
Cotransferred → It is formed from "co-" (meaning together) and "transferred" (from Latin "transferre", where "trans-" means across and "ferre" means to carry). The word describes something that is carried or moved together with something else across a distance.
Think of things being 'carried across' ('transferred') 'together' ('co-') — that's what cotransferred means.
