Abstract
Methods, non-transitory computer readable media, and computing devices that facilitate copy-free data migrations across filesystems. In a first step with this technology, a first set of filesystem metadata associated with a first filesystem is received. At least a portion of the first set of filesystem metadata is retrieved from a first data structure associated with the first filesystem. The first set of filesystem metadata includes a first identifier and a physical location associated with user data. A second identifier, associated with a second filesystem having a different addressing scheme than the first filesystem, is generated from at least the first identifier. A second set of filesystem metadata including the second identifier and the physical location is stored such that at least the second identifier is stored in a second data structure associated with the second filesystem.
