Migrating Sitefinity 3.7 to 5 - Multiple News Providers

Hi Everyone,

I am trying to use the migration tool to move my client's website from 3.7SP4 to 5. 

So I began doing research.  
http://www.sitefinity.com/blogs/joshmorales/posts/11-11-17/migration_webinar_notes.aspx 

It warns in the migration about multiple providers.
Currently, my client's site uses multiple providers for news items and the notes on migration tool aren't very clear on how to go about migrating the providers so that they import correctly in Sitefinity 5.

The instructions say to disable providers and import providers one at a time.
How do you disable providers?

The instructions say to import the providers one at a time, but how does sitefinity 5 know it has two separate providers.  By default the imported, go to the default provider.

If possible, can I get a more detailed step by step approach to how to import multiple providers.

Thanks
