# `Gralkor.PersonalGraphMigration`
[🔗](https://github.com/elimydlarz/jido_gralkor/blob/main/lib/gralkor/personal_graph_migration.ex#L1)

Prepares and verifies the explicit migration of historical private graphs.

Operator identifiers remain unchanged. Connections and configuration references
are supplied explicitly so migration never selects a running application's store.
