For a simple site the 'things to move' usually breaks out to:
- code
Easy, will be in your repository on another location.
- email
Is only really a consideration if you store mail on the server instead 
of locally. Even then it is easy to backup and delaying or even loosing 
a few hours of email is usually survivable for a business. (The simplest 
way to do your backups is to set up another e-mail server and do a 
'forward and keep a copy' on your primary mailserver. That other server 
can even be at your own home since it is essentially  a write-only 
server you just do a bulk upload of .mbox files to your new host if you 
ever need to restore mail that was stored on the server).
- uploads
Easy to do a remote backup over FTP at the interval you are comfortable 
with.
- databases
Depends on database and hoster. Some databases (MySQL, PostgreSQL) allow 
for remote backups and you can do your own backups at the interval you 
are comfortable with. For MS SQL Server you depend on the hoster for 
backups because backups are written to the local filesystem and that is 
typically not accessible to you. (For our MS SQL Server shared hosting 
we do hourly backups and if customers want they can get a copy FTP'ed to 
their site FTP account.)


In order to move it you need:
- a place to host.
- control over DNS so you can point your site to the new host.

Something you should not forget is IP dependencies at business partners. 
If you are doing transactions with third parties that have a list of 
allowed IP addresses you need to make sure you can either update those 
IP addresses instantaneously or you register the fallback IP addresses 
beforehand.



A good way to start planning this is to go over the archive of all your 
communications with your current hoster and see what they had to do to 
get you set up, because your new host probably has to do the same for 
you. Once you have that, set up a mirror on a local development server 
and see what you run in to.
