TFS migration to VSTS

I am in the middle of a migration of TFS (Team Foundation Server) to VSTS (Visual Studio Team Services), and I need to be able to pull information from the code. It seems there are lots of people who have written modules for working with these products, and I want to know from someone who is currently working with these products using PowerShell what is the latest best module or modules to use.

I would like to get history and pull out information on who the last users to work on a project and eventually get into more advanced things.

I am sure there people who use PowerShell to work on VSTS every day, right?

I did a search on PowerShell Gallery and when I search from TFS, I get 12 results and when I search for VSTS, I get 8 results. I see Adam Driscoll has one, he’s a pretty smart guy.

Nobody have any real experience with any of these?

Install-Module -Name Team -Force -AllowClobber -Confirm:$false -Verbose
Get-ChildItem 'C:\Program Files\WindowsPowerShell\Modules\Team\0.1.33'
notepad 'C:\Program Files\WindowsPowerShell\Modules\Team\0.1.33\'
Import-Module -Name Team
Get-Command -Module Team

Install-Module -Name VSTS -Force -AllowClobber -Confirm:$false -Verbose
dir 'C:\Program Files\WindowsPowerShell\Modules\VSTS\1.0.182'
Import-Module VSTS
Get-Command -Module VSTS

I think I have worked out what I am looking for here.
I think Donovan probably has the most active project for VSTS and TFS.
I am sure Adam has unique things he has found most useful.
