nmemo

The nmemo table stores the case memo data after upgrading to iProcess Engine 11.6. Since iProcess Engine 11.6, all the new case memo data is stored in the blob data type in the nmemo table.

You can migrate case memo data in the memo table to the nmemo table when upgrading to iProcess Engine 11.6 or migrate them by using the swutil MIGRATEMEMOS command after the upgrades.
