The original design was built using the GoDaddy Website Builder. For future expansion purpose, I transferred the service to shared hosting with FTP account, where I can install CMS and have access to cPanel. I picked WordPress out of the reason of it being the most popular website management system. To keep the old site running in parallel with the beta version, I created a sub-domain to run the new site and turn the visibility to private before the official release.
For security reasons, I first backed up the raw HTML files before migration occurs. I waited until almost midnight when traffic is negligible enough to take down the old site. Then I transferred the new site onto the original domain. I had multiple cross-platform checks for errors and made minor changes to mitigate a few broken links.
