Organizational Identity Pooling
As of Registry v1.0.0, Organizational Identity Pooling is configured at setup time and cannot be changed. (For more information, see Organizational Identity Pooling.) If you wish to change your Pooling configuration, you must do it before running the Update Database Schema step (ie: running cake upgradeVersion of the upgrade instructions). If you have not previously configured Pooling, the default setting will be unpooled. Once the upgrade to v1.0.0 is complete, Pooling will be fixed at its current setting.
Note it is no longer recommended to change the Pooling setting of an operational instance, so you should most likely leave in place whatever setting you currently have.
