Upgrading from v2 to v3 v2 and v3 are functionally equivalent making the upgrade pretty straightforward. v3 requires Go module support and therefore Go 1.11 or higher. Upgrading from v2 to v3 is as simple as:
Enabling Go modules on your project (env GO111MODULE=on go mod init) Updating the import path of the goa package to goa.design/goa/v3/pkg Updating the import path of Goa package X from goa.design/goa/X to goa.
