So you are currently hosting a Content Management System (CMS), for this example WordPress, with a hosting company and, are looking to move your site to another server or company.
One of the most important pieces of information you should check before doing the migration and cutting over the DNS entries to the new service:
What version of PHP am I currently running and what is on the new service?
If you have a PHP mismatch, you can end up with strange PHP errors when loading your pages on the new service.
How to find out which PHP version you are running:
1. Open Notepad (or your favorite text file editor).
2. On the first line, copy and paste the following:
<?php phpinfo(); ?>
3. Save the file as phpinfo.php
4. Upload the new phpinfo file to both the old and new server in this example location:
/domainexample/public_html/phpinfo.php5. Browse to the phpinfo.php file on both servers http://www.yoursite.com.au/phpinfo.php
6. Compare versions and make sure all components match.
7. Make sure you remove this file once you have actioned your check.
