Another task of web maintenance is moving a site from one web host to another.
Today I've got a site that has to be moved from its current web host.
The main body of this site is HTML with three php powered subsystems;
Now this sounds like a web maintenance task that is not too difficult.
As always the killer is in the details.
The thing you want to do is to move at least a day before you have to shut down the old host. In the test phase after moving I always want to be able to look at the old site. Mostly you will have the new site up and running as a subdomain on the new host and the 'old' site still running on the old host under it's domain name (for this test to work you need to have different domain name servers).
The steps I take when moving a web site from one host to another are;
After doing all this it should be smooth sailing.
After checking everything it is time to switch the domain name servers so that the domain name points to the new host and then we can test some more.
One point I'd like to mention is that the DNS servers should be different (old, new), otherwise you will experience down time as long as 48 hours.
I'll update this post as we move along.
