Migrating wpmu blog to new host
I have job to transfer wordpress multi user to new host. The wpmu system currently host 400+ with subdomain type.
The old host and new host use same operating system FreeBSD dedicated server but with different version.
The procedure for move wpmu to new host not different than moving ordinary wordpress blog.
Preparing and packing
1. Dumping mysql database
# mysqldump -udtonet2 -pdotnet22008 dotnet2 > dotnet.sql
2. Packing all files to one tarball
# tar cvzf wordpress-mu.tar.gz wordpress-mu
3. Transfer the file to new host
# scp wordpress-mu.tar.gz erau@172.88.1.8:/home/erau
Password:
wordpress-mu.tar.gz 100% 402MB 13.9MB/s 00:03
#
4. Change dns setting
CPU Throttle and Cache
Almost 20 host successfully move to bluehost while I left others in other web hosting for internet marketing purpose.
I just wnt to say that I’m impressed with cpu throttle technology that bluehost use in their shared hosting.
As you can see in the picture I got ‘throttle’ every hour but I still can get my site accessed during that period which is cool bro.
I also implement Cache Solution for WordPress that reduce throttle time to almost 30% off.
Kudos to cpu throttle technology and wordpress cache!

During migration the files of my website and blogs (around 1,7 GB) I’ve found many files in wordpress database created with some types :
- Statistic files (from statpress plugin)
- Top 10 file (from top 10 plugin)
- Revision file (from built in ‘post revisions) wordpress system)
Wow, since I’m the only editor of the blog I decide to manage this feature more efficient.
Don’t Store Revisions
Looking around for wordpress plugin I decide to use Revision Control wordpress plugin.
From the description :
Revision Control is a plugin for WordPress 2.9+ which gives the user more control over the Revision functionality.
The plugin allows the user to set a site-global setting (Settings -> Revisions) for pages/posts to enable/disable/limit the number of revisions which are saved for the page/post. The user may change this setting on a per-page/post basis from the Revisions Meta box.
The plugin also allows the deletion of specific revisions via the Revisions post metabox.
After install and activate the plugin I can access from Settings sub menu named ‘revision’ :
I decide to set ‘Do not store Revisions’ for Posts and Pages. Click save and I’m saving some db space 
See you in other post and stay health!
