Migration Approach Recommendation

Recommended: Bluefield (Selective Data Transition)

SAIL has 5 independent ECC instances with significant per-plant customizations, especially in PP (Production Planning) and QM (Quality Management) for steel-specific processes. A pure Brownfield would carry forward all 5 instances separately. A Greenfield would lose decades of production configuration.

Bluefield allows you to: (1) consolidate shared processes (FI/CO, MM, SD) into one global template, (2) selectively migrate plant-specific PP/QM configurations only where validated, and (3) leave behind obsolete Z-programs (estimated 2,100 objects unused in last 24 months).

EY precedent: 3 of 4 similar steel/metals EY projects used Bluefield. Average timeline: 24 months. Risk: data deduplication across 5 vendor masters.
