> ## 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.
>
