When you have familiarize with the new hosting account and ready for the actual move, first thing to do is backup your data at old hosting account, data as in the website program scripts, database if it is being used, email addresses in mailing list, list of email accounts etc. double check twice to ensure you have all all the data backup, things can be too automated and chances are you might have overlook something that is not being used often but needed. you don't want to missed out any single pieces of important data of your website.

Upload data to new hosting account

If you are still having the test site in your account, clear up everything.

Upload the data you have just backup to the hosting account, setup each piece of the data accordingly, you may need to make small changes here and there in your program scripts, things like file path, database connection strings etc. Remember to setup identical email addresses as well, this can ensure email messages to your domain is being placed in respective mailboxes the same way as in the old web host.

Check through everything at new web host

When you have all data setup, check through your website thoroughly to ensure nothing is missing or not functioning as expected, there are bound to be small little things here and there that need minor changes, fix them and retest again to ensure it is working as expected.

Please ensure you are testing your website like a normal visitor, don't just expect a web page that show up correctly on browser window is going to function properly, for example those forms, you will never know unless you hit the submit button, you don't want to find that out by your website visitors later, this can mean loosing orders if this is happening on your ordering form, does that sound serious ?

Change domain nameserver

After you have tested your website thoroughly, and are confident that everything is working as expected, you can choose a less traffic period to your website, and issue a domain nameserver change for your domain, note that this change is going to take approximately 24-72 hours to complete, and this depends on the update schedule of individual ISPs, the more frequent the ISP picks up update, the faster the visitors using that ISP gets directed to your new hosting account. That say, during the nameserver update, some visitors will be visiting the old hosting account, and some will be visiting the new hosting account, and the traffic to old hosting account will decrease as more ISPs pick up the nameserver update, check your webstats for both hosting account and you will notice the difference.

When you are only seeing traffic to your new hosting account and no more traffic to your old hosting account, that means the transfer has been completed, you can do a final sweep of data at old hosting account, like email messages etc. so that you are not missing anything sent to old hosting account during the transfer.

You know what? you have just completed the transfer without your website visitors even noticing it !
