## 3.3. Upgrading from 3.0.0 to 3.0.1

Install OLAT as described in the installation chapter but DON'T RUN 'ant dbsetup'!! We recommend to move your existing installation from PATH_TO_YOUR_OLAT/olat3 to PATH_TO_YOUR_OLAT/olat3.0.0 and install the 3.0.1 package as your new PATH_TO_YOUR_OLAT/olat3. All user data is located in the olatdata directory which should not be located in the PATH_TO_YOUR_OLAT/olat3. The olatdata directory and the database won't be changed when installing the new code. Example linux shell commands:

    #cd PATH_TO_YOUR_OLAT
    #rm olat3 (if olat3 is a symlink, otherwise: mv olat3 olat3.0.0)
    #unzip OLAT-3.0.1.zip
    #ln -s OLAT-3.0.1-FINAL-20040804 olat3
    #cd olat3
    #vi build.properties
    #ant config-all
    #ant install

Update your database manually according to PATH_TO_YOUR_OLAT/olat3/database/alter_3_0_0_to_3_0_1.sql

Now start tomcat. The first launch might take some time.
