Table 1 Checking whether the source database tables contain primary keys

Check Item

Whether the source database tables contain primary keys

Description

If tables to be migrated in the source database do not contain primary keys, the migration may fail.

Item to Be Confirmed and Handling Suggestion

Item to be confirmed: The tables to be migrated in the source database do not contain primary keys.

Handling suggestion: Create a primary key for the table. If the table does not have a primary key to uniquely identify every row and the network connection is unstable, the data in the destination database may be inconsistent with that in the source database.
