I used phpMyAdmin to make the changes. I have found the solution and wanted to share in case anyone else comes across this. The issue was in a background image that had been uploaded in the development environment. When the page was rendering it was trying to call that image from the old IP. I discovered the root cause by using Developer Tools in Chrome to view the page source. I corrected the issue by re-uploading the image from my production environment, thereby changing the source IP. Thank you for your response.
To further respond to your suggestions, I didn’t do a database migration so no migration tools were needed. I imported the entire operating system from one virtual environment to another, specifically to avoid the complications involved with that. It was just a matter of adjusting the domain name/IP addresses within the MySQL database at that point.
