+## How can I convert a Block Storage legacy volume into a Block Storage Low Latency volume?
+
+Currently, there is no direct way to change the storage class of a volume while preserving its ID.
+
+However, you can use the snapshot export/import feature as a temporary solution to transition a Block Storage legacy volume into a Block Storage Low Latency volume.
