Help Guide Me Through The Transfer From Sharred Hosting to Dedicated Hosting

I have 3 Shared Hosting accounts with Hostgator (2 Baby plans & 1 Business plan). I've purchased the Hostgator Basic Dedicated Server Plan. Hostgator will move all my websites to the dedicated server. I would like your help with the proper setup of the new server. I want to make sure I don't make any mistakes in setting this up that would shut down any of my existing websites or emails. I'd like your guidance in setting up the following (I may ask you to actually make the changes): * Registering my name servers * Need to create the name servers at Godaddy * Add the necessary A records to my domains * Make sure I'm telling Hostgator to move all my domains so that there are no problems. Many of my sites are Wordpress sites and I need to be confident that they will be moved correctly by Hostgator and would like you to oversee that move. * Configure my cpanel or explain how I can do future Wordpress installs. I previously used Fantastico to install Wordpress on my hosting and I don't see that option. * Make sure my SSL certificate is working after the move on one of my domains * Make sure all my emails are working * Any additional work/help that is needed Basically I just need you to help me with this transfer so it goes smoothly. Thank you
