This plugin is half usable it is moving only some of data for all other data you need to enter manually with this incomplete migration.
But keep in mind that not all vendor data can be editable in Dokan dashboard, you need "switch users" plugin so that you can login as vendor and enter all missing data.
So if you have online shop that is on WC Vendors with lot of data and vendors.. this is gonna make you big work.
We are owners of dokan premium and this type of start working with Dokan is unacceptable. I hope that my opinion will change ...
