Migrating to DreamPress

I should start with the note: You do not need to do this. We’re finishing up the last bells and whistles on a script that will handle all this for you if you have a One-Click-Install, but if you really just can’t wait or had a manual install, here’s what you’ll need to do. Keep in mind, there will be about an hour where your hosting will ‘vanish.’ In the words of Ford Prefect, don’t panic.

 

Again, you don’t have to do this. We will have a magic button soon enough. That’s why this isn’t going up on the Wiki, it’s really not going to be (long term) useful except to people who love experimentation.

We have a magic button!

But if you still want to do it manually, read on.

So you saw the news about DreamPress and read our bragging post about it? You got super super excited and then bummed, because the magic button isn’t done yet? Well… Okay, you can migrate manually (I did it for this site yesterday), but you need to know shell. You can do all this with FTP, but it’ll take way longer.

If you just want to make a new domain, read DreamHost Wiki: DreamPress, and you’re good to go! Otherwise, pull the hat down snugly, because here we go!

1. Remove Hosting

1-removehosting

Yes, I know. It’s scary. By removing hosting you will turn your site to DNS only. This is OKAY. Your files and your DB will remain exactly where they are. The Remove button is right under ‘Fully Hosted / User : elftest‘ so just click that.

2-see-DNSonly

See? Now it’s DNS only.

2. Add DreamPress hosting

Go to https://panel.dreamhost.com/index.cgi?tree=domain.wordpress& and add a new site.

3-addDP

You should see a happy green box telling you that it will take 15-30 minutes to provision you the site. Sorry about the wait time, but we’re actually building you the server stuff on the fly. It’s special.

4-success

While you’re waiting, let’s get some things done.

3. Export the old DB

Everything is perfectly safe and sound, so just go ahead and do that. Save it locally to your computer.

Go to https://panel.dreamhost.com/index.cgi?tree=goodies.mysql& and log in to your SQL database. The directions are the same as our normal Backup MySQL ones, so just go and do that.

If you’re Command Line savvy, you can do this via WP-CLI.

ssh oldaccount@oldserver.dreamhost.com
cd example.com
wp db export

That will reply with “Success: Exported to example_com.sql”

By the way, you’ll need to have the server name (not your domain name) in order to SSH in, as we’ve already pointed your domain to DreamPress. It’ll be something like ps10000 which makes your SSH ps10000.dreamhost.com. You can leave the SQL file there, we’ll pick it up later on in the show.

As soon as you get that email saying “Yay! DreamPress for you!” we’ll ignore the email’s directions and skip on to…

4. Get the new credentials for both SQL and SFTP.

On the DreamPress page, you’ll see your new site info.

5-newinfo

You’ll be able to find the new passwords at the usual locations. In the case of the user account (which will be something like wp_kxezav), you’ll want to set it to something you know. While you’re in there, change the account type to “Shell account – allows SFTP/FTP plus ssh access.” I personally also check to disallow FTP, for security. I also like to rename the account something like ‘ElfTest – DP’ so I know this account is for ElfTest on DreamPress.

By the way, you may wonder “Why can’t I have one ID for all my domains on DreamPress?” and the answer is twofold. First, we’re charging you per site. Yes, site. Secondly, security. If one account gets hacked, the others are safe. This is a good thing!

5. SSH into your new account

It’ll be ssh wp_kxezav@ps1121212.dreamhostps.com or such and this will dump you into not the domain, but the folder above it. This is important! You need to be in the example.com folder in order to do anything. Notice also how the domain is suddenly dreamhostps.com and not just dreamhost.com? Also important.

By the way, if you’re going to be using a lot of SSH, you should set up passwordless SSH access. It’s perfectly safe (in fact, safer than entering a password), and has to be set up per computer but .. how many of us use more than one computer? Hush, geeks.

6. Super power time! Let’s copy everything over!

Actually, let’s delete everything first. Yes, I know what I just said. There are reasons. This is just faster. I’m super lazy, so I first opened up wp-config.php and copied the SQL data for the NEW database.

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'example_com');

/** MySQL database username */
define('DB_USER', 'examplecom1');

/** MySQL database password */
define('DB_PASSWORD', 'likeaflaninthecupboard');

/** MySQL hostname */
define('DB_HOST', 'mysql-1.example.com');

Obviously changed for my protection. You’d never publicize your passwords. Right? RIGHT? Good. I saved this to a text file on my laptop for the time being. Now let’s delete:

ssh newuser@ps1121212.dreamhostps.com
cd example.com
rm -rf *

This wipes out everything in my domain’s folder. Make 100% absolute sure you got the right folder! Once you’ve done it, let’s copy things over!

scp -r olduser@oldserver.dreamhost.com:example.com/ .

SCP is ‘Secure Copy’, and is a fancy pants Unix Command. I’m fond of it. You’ll notice that I said to use ‘oldserver.dreamhost.com’ and not ‘example.com’ and this is because we’ve already pointed your domain to DreamPress. Zoing! When you do this, you’ll be prompted for a password.

Then you’ll get a mile of stuff like this:

wp-config.php                                                  100% 3583     3.5KB/s   00:01
xmlrpc.php                                                     100% 2719     2.7KB/s   00:00
readme.html                                                    100% 9177     9.0KB/s   00:00
admin-bar-sprite.png                                           100% 2470     2.4KB/s   00:00

This is SCP copying everything over, safe and sound.

7. Change your Database Stuff

There are two parts here. First you want to copy that DB stuff you saved before into the wp-config.php file, replacing the configuration you had there before. Second you want to import that backed up database into the new DB.

You can do this via phpMyAdmin if you want, but if you’re using wp-cli (and you should, it’s awesome), you can do this:

wp db import example_com.sql

Whaaaaat? How did that work? Remember when you exported on the old setup and then SCP’d the files over? Guess who came with! That’s right, you slipped your DB over nice and fast, and boom goes the dynamite, you’re in.

8. Have a beer!

I always end things with a celebratory something. Your URLs didn’t change, so you’ve got nothing to worry about. Once you’re sure everything’s good, go ahead and delete the old user ID as long as you are 100% certain you’re not still using it!!! Remember, a lot of us use the same IDs for multiple domains.

    Thanks for this post. It was really helpful and I’m too impatient to wait for the automated tool. I had one issue you don’t mention that might be worthwhile here. After the migration was complete and I was able to get to it (slight DNS delay) only the homepage would load. None of my links worked even though I could access the wp-admin panel and see all of my posts and pages. It took my wp expert telling me to visit and resave the permalinks page to resolve that problem. Did I do something wrong or might that snag some others.

    • Ipstenu says

      Sounds like your .htaccess didn’t come along with you. Re-saving the permalinks probably would have fixed it.

    I buy my domains on Go Daddy and put a series of numbers in go daddy to tell them where to point the domain. So If I make a hosting change – what about my numbers on go daddy? Do I get numbers from the new host and put them in the go daddy form. When do I do that? Will changing hosts break all of my themes and plugins? I appreciate your help on these questions.
