Logging

Summary log

Contains the high-level overview data of the migration. Summary lists connections, migration stages, number of tables, and the outcome.

Error log

All errors occuring during the migration will be listed here.

Warning log

Warnings are notices that are still not exactly errors. For example, if we note several indexes covering exactly the same table columns, we will only create one of them and output a warning so you know about it.

SQL log

All the SQL statements sent to the target database are in this log. Please note that bulk copy bypasses SQL engine for performance reasons and will be show here just as a comment.

Error SQL log

Of all SQL statements sent to the target, this separate log file contains statements causing the target database to report an error.

JSON log

For automation purposes, all of the important information is available in a structured JSON log.
