1 - Backing up config.yml and default.yml

Before proceeding, you have to save your current configuration files to migrate them to the new version.

  1. These files can be found in the installation path of Write-Back under apache-tomcat/webapps/twbe/WEB-INF/classes/config.yml and apache-tomcat/webapps/twbe/WEB-INF/classes/sites/default.yml. If you have more sites configured besides default you will have to save those as well.
  2. Please save these files to a location that you can access later.

2 - Backing up database driver

Besides configuration files, you'll also have to backup the driver for the database you are currently using; save it to a place that you'll be able to reach later.

  1. It can be found under apache-tomcat/webapps/twbe/WEB-INF/lib. The PostgreSQL driver, for example, is postgresql-42.2.5.jar.
  2. Please save these files to a location that you can access later.
