When you use eazyBI in several Jira environments then in each environment you should use separate eazyBI database (that you specify in eazyBI settings).
If several eazyBI environments will use the same eazyBI database then it will result in data corruption.
eazyBI database connection parameters are stored in the
JIRA_HOME/eazybi.toml configuration file. If you copy the Jira home directory to different environment then please update the database connection parameters in this file to point to a separate eazyBI database (or remove database connection settings and then specify them from the eazyBI settings page).
If you would like to copy an eazyBI database to different environment then you can use the database migrator.
