## Migrate data from QuickBuild PREVIEW2 and PREVIEW3

To migrate from QuickBuild PREVIEW2 and PREVIEW3, please go through the following steps:

1. If you are using MySQL as database, edit file "config.properties" to connect to your existing MySQL database.

   | Note
   Please do not simply overwrite "config.properties" with the same file from existing installation, cause this file has been changed since PREVIEW3.

2. If you are using HSQLDB as database:

   - Remove the "data" sub directory of QuickBuild 1.0.1.

   - Copy "data" sub directory from existing installation to QuickBuild 1.0.1.

3. Copy "publish" sub directory from existing installation to QuickBuild 1.0.1.
