We do not have the option to convert a standard share to distributed share or a distributed share to a standard share as of file version 3.7. We have a feature request open with Nutanix engineering to enable this feature.

The workaround is to create a new share and move the files to the new share using data migration tools. Migration Tools like Robocopy, PeerSoftware and Datadobi can be used.

Details on the various migration tools can be found in the below portal document:
