testing move of WordPress 3.9.2 from Linux host to Windows server 2008 with IIS

I am new to WordPress and this was my first attempt to move WordPress 3.9.2 from a Linux host to Windows server 2008 with IIS 7.

I glanced at the threads https://www.ads-software.com/support/topic/wordpress-blog-moved-from-linux-to-windows-iis-server?replies=4 and link https://codex.www.ads-software.com/Moving_WordPress

I used the Duplicator plugin https://www.ads-software.com/plugins/duplicator/ for the moving process. There were no errors or warnings in Step 3(Test Site) of the move process. I saved the permalinks using the Default option.

The old website registrar was cheapnames.com who has been down for about 2 days so I could not change the website’s A(Address) record to point to the new Windows host computer.

1. Is there a way, I can test, if my move was done properly or not?

2. If I go to https://www.newsite.com, I get a blank screen whereas if I go to https://www.oldsite.com the website appears. Since the files, plug-ins are on the Windows host, I was expecting the website to be available when I type https://www.newsite.com which has the IP address of the Windows host computer.

Does that mean something went wrong? The default page for https://www.newsite.com is index.php which contains

define(‘WP_USE_THEMES’, true);

/** Loads the WordPress Environment and Template */

require( dirname( __FILE__ ) . ‘/wp-blog-header.php’ );

Any suggestions would be appreciated.
