Porting my app from fusionAuth

I have been using fusionAuth and am having a problem with a very simple passwordless login for a year. I have had it with their lack of support. I noticed that they have a document on how to port from auth0 to fusionAuth. Do you guys have a document on how to port from fusionAuth to auth0? Is there any consultant available who has experience in doing such a port? Is there a paid support option to purchase help to do that?
