Drystan.com hosted on a new domain

I'm in the process of migrating the domain Drystan.com, applications, sub-domains, etc. from hostmonster.com to hostclear.com.  I been with hostmonster.com for about 2 years now, but I have noticed that the last few months speed has diminished so it affects the speed of my blog. I spent some time performing cache optimizations and I did managed to improve the speed of the website, but still not to a desirable level so that's when I decided to move to a different hosting service. I haven't migrated everything yet, but I have already migrated my blog and I have noticed page load improvements so that's good.  Now I need to migrate my other applications (e.g. fitness.drystan.com, melissa.drystan.com, etc.).
