How to migrate Wordpress Site from Hostgator to Bluehost manually?

What if the free migrating plugins you are using do not work at all,  or if all else fails, then your last resort would be migrating sites manually. Migrating WordPress site by hand requires a lot of effort and time, but for me this is the safest way to retrieve all your files without experiencing lots of problems. 

I'm not a programmer nor expert in Cpanel, but once you dedicate your time in "learning by doing", all other difficult things become easy. I'll share with you how I migrate WordPress site with less headaches.
