Changing Web Hosts? - Know-How With This Step-By-Step Guide

Every
webmaster cringes at the thought of moving hosts.
Like moving your home it can be messy and sometimes
problems arise. But if you follow these simple
steps, your move will be less painful.
Backup
Backup Backup
If you've been diligent with your backups, you've
got a lot of insurance to fall back on yet always
make the latest backup. If you haven't, before
you do anything else, do a backup now. Backup
anything and everything you can and don't forget
your database if your site relies on it. Save
at least 2 copies and store them separately.
One for you to work with, and the other as an
archive. Do not underestimate how easy it is
to copy over these files as you make changes
or simply mess it up.
If
you're moving to a host who has as different
control panel, make a manual backup by downloading
all your files because different control panels
may not be able to restore the backups made
by your old host. They also have different directory
structures so your file trees will be in a mess.
If you need to, make a small note file with
notepad with memos for you to remember the old
server configurations. This will help you as
you make changes on your new host server and
save the confusion moving back and forth between
hosts. Remember to make the correct transfer
type (ASCII or Binary) as you download. If your
download is not right chances are you'll have
a tough time getting your site to work on the
new host server.
If
server logs are especially important, remember
to backup those too. There is no good way of
moving logs yet because different hosts may
log statistics differently. So the best thing
to do is to download it and use a log analyzer
on your computer to make references to later
on.
Gather
Odds & Ends
1. A Good FTP program which you should have
by now
2. Get your new host server's DNS
3. It's also helpful to have a script that tells
you the server environments installed on your
new host server for quick references.
4. Get the temporary URL on your new host so
you can check your site before you make a DNS
change.
5. If you have your host control the domain
inform them not to change your DNS until you
tell them to.
6. If you run scripts:
Ÿ Get a copy of the original installation
guide and the script. Sometimes after moving
the scripts just do not work right so you might
need to install the script from scratch.
Ÿ Get a list of all the server paths such
as Perl, Sendmail and home directory on your
new server.
Ÿ If your script needs special server modules
or programs ensure they are installed and where.
Even though these might be covered before you
ordered the account with the host but sometimes
your host has removed it or haven't installed
it yet.
Inform
Your Visitors
It is common and good practice to inform your
visitors and customers of the server move. If
you run a e-store, this helps assure your customers
you have not fled with their money if there
is any downtime. Also give an alternate email
so you won't lose emails in the transfer. You
might also want to give periodic updates prior,
during (if there is downtime) and after. If
your site is large, doing this is helpful because
your visitors can alert you whenever there is
a part of the site not working.
Moving
Day
Try to schedule the move at a time where there's
least traffic. Backup again just before you
do the move so you'll have the latest data.
Start by first copying or creating your custom
error pages onto the new host server. Put a
small note in there about the move. You can
always remove it later. Then upload the most
visible parts of the site first i.e the main
pages then move on to the less critical parts
of the site. If you have a large site with many
divisions you might want to split them across
different days and instead move the least critical
first. Just ensure you always do a backup before
you do any moving. Use the temporary URL to
check your site, visiting as many pages as you
can.
Changing
DNS
Once you're satisfied, change your DNS over.
This typically takes about 24-48 hours so you
have time to make some minor changes if need
be. You might want to also take this time to
modify your old site's error pages to inform
your visitors of the move and give a new URL
if there are URL changes. To help you determine
if the DNS has resolved, make a small change
on the new pages to differentiate between the
old and the new.
Monitor
After you've moved and the DNS resolved, do
not release the old account yet. Keep it as
long as two weeks running concurrently. Go back
and check the old servers for activity. Check
your old email account and if you have a web
based contact method on the old server check
to see if any communication is left there. Once
you're comfortable all email and traffic is
correctly directed to the new host server, you
can cancel that account.
