## The Procedure

1. Disable your Plugin
2. In your JIRA database, please delete all the tables, sequences, and other objects which begin with:
  1. AO_0456E7_ - for **BigPicture**
  2. AO_8AC478_ - for **BigGantt**
  3. AO_DA6AB9_ - for **BigTemplate**
3. Execute the following scripts:
  

Depending on the plugin's database you would like to alter, 'AO_0456E7_#' should be replaced with 'AO_8AC478_#' or 'AO_DA6AB9_#' in the script given above. 

4. When the previous query returns result and there were records to delete, you have to restart Jira Server.
