MIGRATECore learning content / activity / progress / assessment · 35 columnsProposed target
Transform into target course, module, attempt, grade, completion, credential and content models
Migration rule
Preserve history and relationships; retain original IDs in legacy_id fields
Verification required
Plugin behavior, attempt state, grading rules, file references and completion logic require application-level verification
