+### Snapshot configuration migration
+
+The latest snapshot YAML configurations introduced in dbt v1.9 (such as [`snapshot_meta_column_names`](/reference/resource-configs/snapshot_meta_column_names) and [`dbt_valid_to_current`](/reference/resource-configs/dbt_valid_to_current)) are best suited for new snapshots. For existing snapshots, we recommend the following to avoid any inconsistencies in your snapshots:
+
+#### For new snapshots
+- Use the latest snapshot YAML configurations when creating new snapshots that didn't exist previously.
+
+#### For existing snapshots
+- Migrate tables &mdash; Migrate the previous snapshot to the new table schema and values:
+  - Create a backup copy of your snapshots.
+  - Use `alter` statements as needed (or a script to apply `alter` statements) to ensure table consistency.
+- New YAML config &mdash; Convert the YAML configurations one at a time, testing as you go. 
+
+If you use one of the latest configs, such as `dbt_valid_to_current`, without migrating your data, you may have mixed old and new data, leading to an incorrect downstream result.
