• The --connection-name argument is missing the short alias (-n/--name). Consider adding -n and --name to match other commands and improve discoverability.

Are we starting with 1.x here? I thought we would need to keep sem-ver below 1 for private preview: e.g. - 0.1.0

[lasuredd-msft]

The minimum product for release is 1.x, extensions in preview have 1.xbx, once we move out of preview then the version number starts from 1.x.

do you think az azure-data-transfer xx is a good name? cauz, az and azure-* have the duplicate meaning here.

[lasuredd-msft]

Moved away from the duplicate azure naming , renamed to data-transfer
