What is a legacy volume?
Applicable Products
QTS
Overview
A legacy volume is a volume created before QTS 4.0. Existing volumes become legacy volumes after upgrading QTS from an earlier version to version 4.0 or later.
Legacy volumes can still be used for data storage, but their behavior and status will not be consistent with other volume types. They also cannot benefit from the latest QTS features such as snapshots.
Recommendation
If you still have legacy volumes in QTS 4.3.4 or later, we recommend that you back up all data on the legacy volumes, create one or more new volumes, and then restore the data to the new volumes. This will enable you to fully utilize all features in Storage & Snapshots.
