Users can’t login after migrating to SharePoint 2013

As long as you don’t do this, users will not be able to access your sites.

To fix this, open the SharePoint PowerShell command line and execute the following script:

Hi, I realize this is an old post but hopefully you can clarify my question.

When I run convert will this affect any windows permissions on my existing production 2010 environment? I have a feeling it shouldn't but just want confirmation before going ahead, Thanks.
