IFC Migration Orchestrator

Drive a complete schema-version migration of an IFC dataset. This is an ORCHESTRATION skill : it sequences the migration workflow, detects the source schema, plans the entity map and the attribute map, flags entities that cannot be migrated, runs the conversion, and routes the result to post-migration validation.

This skill answers one question : how is this model moved from its current IFC schema version to a target version, and what is lost on the way. It does NOT itself hold the entity-level rename and attribute detail : that is ifc-impl-version-migration. It does NOT teach what changed between versions and why : that is ifc-core-version-evolution. It is the conductor ; those two skills are the score, and ifc-agents-file-validator is the final check.

Migration is inherently LOSSY and BEST-EFFORT. There is no official buildingSMART document that prescribes a single correct migration path. ALWAYS treat a migration as a planned, audited transformation, NEVER as a guaranteed round-trip.
