How to move WordPress site to another server with zero downtime

The Hunchback of Notre Bresil

Here is step-by-step tutorial on how to move your WordPress site with zero downtime.

  1. Backup the database from the old site and import it to the new site. Pay attention to database names.
  2. Change your wp-config.php in the old site to point to the database on the new site. Your old site will now run using database based on the new site and once you change the names ervers new site will have the up to date database. (You may want to check with your new hosting if they allow outside database access first. If not, you can skip this step and transfer the database at the end, when the nameserver change propagated)
  3. Backup your entire WordPress installation from the old site (this will include all your uploads, themes, plugins)
  4. Unpack your WordPress installation to the new site
  5. Change wp-config.php on the new site with new database details
  6. Change the nameservers to point to the new site
  7. That's all now you only need to wait :)

Since nameserver propagation can take up to one day, step 2 allows you to have up to date database at the moment it happens. Downside to this is slower site response in the meantime because site still runs from the old server and the database is on the new. But if you do this over the night or periods of low traffic it won't be that noticeable and you will not lose any comments or other activity on your site.

    I followed all these steps BUT my links now don't work.

    I grabbed a backup of the old site, then I used fantastico to install a new Wordpress account on my new server.

    I then did a "drop" of the contents of the new MySQL database and did a restore from the backup .sql file, which seemed to go ok.

    I uploaded all the old files provided, like templates, etc. I modified the config file to know the new database name and created the correct username and password on the server.

    I then changed the name servers to point to lunarpages and this morning it all came up looking like it was going to work.

    The front page comes up and looks fine.

    I can log into the wp-admin and everything there seems to work fine, all the old pages are listed and I can even modify the article called "home" and the changes appear fine on the website.

    BUT - none of the links from the front page work. They all give a 404 error.

    For example "about us" permalink listed in the admin editor matches the link that appears when you click the about us link on the front page, yet the two are not matching up

    Any idea why?

    Vladimir, this works great. I just had to change Host. I used your procedure for a check list. When the nameserver changed in a few hours, every thing fell right in place. I don't think I had any down time.

    Thanks Bill

    I have changed servers and I've changed the wp_config.php but I still can open my blog nor can I get admin
    to open. All I get is a blank page. Anybody have any suggestions

    So will this work if I want all the widgets and plugins and settings to remain the same? I want to be able to just move it over to another server and have it be the same as it was on the previous server. Is this possible.

    Before I could activate my migrated wordpress installation (I just duplicated my installation on the same server) I had to change the value 'siteurl' in the database table "wp-options" by hand. Otherwise I would have been redirected to the old wordpress installation.

    Hi Guys.

    I am just wondering. Will it be possible to install a fresh copy of Wordpress and over write the new database with old database?

    Care must ensure that both copies of the Wordpress MUST be of the same version to prevent conflicts?

    I am going to change server soon and it is getting me paranoid with so many suggestions and ways to move a Wordpress blog.
