How to remove an on-premises project - EngageOne Video

On-premises solution such as a virtual machine on Virtual Box, with a CentOS setup.
To remove project on on-prem installation you need to:

1. Take it away from /var/rtc/published/<project_name>, either by removing it, or by moving it outside of /var/rtc/published. 

2. Clean up the database, as you have to drop or rename schema related to project. It's usually called project_name_environment, for example 'test_project_production'. 

3. Afterwards you will be able to deploy a project once again - just follow the instructions the same way how you did it for the first time as laid out in the help and documentation.
