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: - 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.
- Get a list of all the server paths such as Perl, Sendmail and
home directory on your new server. - 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.
