1. A method for performing an in-place conversion of a data-storage volume from a first data volume format to a second data volume format, comprising: creating a fence around a data-storage volume to prevent data traffic to the data-storage volume during in-place conversion, the creating a fence comprising allowing one or more protocols to shutdown prior to the in-place conversion; and converting the data-storage volume from a first data volume format to a second data volume format in-place within the data-storage volume while the data-storage volume is mounted, resulting in the data-storage volume in the second data volume format, the in-place conversion comprising not utilizing a second data-storage volume, the converting comprising: querying a volume manifest of the data-storage volume to identify a first set of features associated with the first data volume format; querying a feature mapping table to identify a second set of features associated with the second data volume format; and determining if in-place conversion of the data-storage volume can be performed based upon determining whether the first set of features is implemented differently than the second set of features.
