While running the below command,

$WebAppName = "http://yourWebAppUrl"
#THIS SHOULD BE THE ACCOUNT THAT IS RUNNING THIS SCRIPT, WHO SHOULD ALSO BE A LOCAL ADMIN
$account = "yourDomain\yourUser"
$wa = get-SPWebApplication $WebAppName
Set-SPwebApplication $wa -AuthenticationProvider (New-SPAuthenticationProvider) -Zone Default

this will prompt about migration, CLICK YES and continue //

After clicking Yes, Getting Access Denied.

1. Management shell Running as Administrator
2. User login having local Admin Permission
3. User Login is SQL Dbo.

Answer 1

I have followed the Anders Aune comment and checked the permission and solved my problem.

// Make sure the user has the right permissions, you never know what people have done with the farm. Link: technet.microsoft.com/en-us/library/ee806878.aspx#section3 – Anders Aune //

Thanks to Colin & Rajesh...

Answer 2

Could you try this instead:

$WebApp = Get-SPWebApplication http://url
$WebApp.UseClaimsAuthentication = "True" 
$WebApp.Update()

Answer 3

$webApp = Get-SPWebApplication "http://mysites.com" $webApp.UseClaimsAuthentication = $True; $webApp.Update() $webApp.ProvisionGlobally() $webApp.MigrateUsers($true)

Try and update the status which help others.
