# Kusaba X Database Migration
|
||||
|
||||
## About
|
||||
This script pulls board information, posts and images from an already existing [Kusaba X][k] installation and replicates them in [Tinyboard][o]. It should be helpful for those who already use Kusaba X][k], and want to switch over to Tinyboard.
|
||||
[o]: http://tinyboard.org/
|
||||
[k]: http://kusabax.cultnet.net/
|
||||
|
||||
## Requirements
|
||||
1. [Tinyboard][o] >= v0.9.2
|
||||
|
||||
## Use
|
||||
1. Install Tinyboard (>= v0.9.2) normally.
|
||||
2. Download and place `kusabax.php` in the root folder of Tinyboard.
|
||||
3. Edit the script and fill in your Kusaba X configuration. You can find KU_RANDOMSEED from Kusaba X's config.php file.
|
||||
4. Run the script in a web browser.
|
||||
|
||||
## Documentation
|
||||
Visit the Tinyboard development wiki at <http://tinyboard.org/wiki/> for help.
