moving from subdir to subdomain on new server

I don’t want to upgrade the old WPMU, it needs to keep running as is …

I did created a new site in the new WP (3.0.5) , but how can I move content from the old to the new . I though that export from old then import (xml file) in the new site was the way to go , isn’t it ?
that’s what I did, unfortunatly after the import no content appears in the new site. I suspected that it was because the export was made on a subdir WP, whereas the new site is on WP based on subdomain … but maybe I am wrong ? what is the best way to move content in my case:
“blogs from a WordPress MU 2.8.4 configured in subdir to a WordPress 3.0.5 configured in subdomain” .

Thanks .

thanks for the hint to look a the xml file.
indeed , only one post out of 10 was there in the export file !?
maybe a problem of file size somewhere ..
I did it again (on site instead of offsite through ADSL box …) and it worked better.
there’s still a problem about files upload, for example at the end import process I received:

Import WordPress
Failed to import Media “photo.png”
Failed to import Media “article-de-mi-kun.pdf”
Failed to import Media “la-vie.pdf”

I manage to copy those file from old blogs to new one

[root@oldblogs /vservers/blogs2/var/www/html/blogs/wp-content/blogs.dir/11/files]
$ scp -r * root@blogserver:/var/www/html/wp-content/blogs.dir/5/files/

but I still have to manually correct links to the files in the new blog

<a href="http://blogs.it-sudparis.eu/blogs/chine/files/2008/10/la-vie.pdf" title="la-vie.pdf">la-vie.pdf</a>

to

<a href="http://chine.wp.it-sudparis.eu/files/2008/10/la-vie.pdf" title="la-vie.pdf">la-vie.pdf</a>

fastidious, but it works.
thanks .

Ok, thanks for the tip, indeed I would rather change globally within the xml file URL before importing .

One more request . Is there a way to import users also ?
On some blogs there are dozens of contributors, authors, how can I export then from the old one and import them to the new WP plateform.

I don’t see a native export/import tool for users in WP !?
shall I use a plugin ? something like this :
http://wordpress.org/extend/plugins/wp-export-users/
is their a better one, or a better solution ?

Thanks .

I don’t want to duplicate my old WP, because the new one uses federated Identity (shibboleth federation + SSO http://wordpress.org/extend/plugins/shibboleth/) and it’s kind of a hard work creating an extra shibboleth Service Provider .

The positive thing on shibboleth SSO is that I don’t care about user passwords, they out of the WP database.

What i need now is a way to export at least username (+email adress) from the old one, and import then on the new one, I don’t care about userId numbers because apparently when importing the XML of posts, pages etc … the import process allows my to match old users to new ones.
The thing is here to have a least the username be created in the new blog in order to match them to the XML file .

So , still no appropriate native or plugin to export them import usernames ?

Thanks.

very good that http://www.xkcd.com/806/ webcomic , didn’t know about it , are you one of these geek tech support 😉

post import comes with its associated authors, but then the import process (step2 as far as I can remember) allows me to match authors to current users of the new WP site. unfortunatly I don’t have all users present and associated to the WP site a that time, That’s why I need to import users before import . I’am afraid there is no magic and simple solution, unless the native export + import tools manages users creation at post import time .

Thanks for your help .
