EWI Index

The VB6 AI Migrator helps with this process by inserting different Errors, Warning and Issues information messages (hereafter referred to as EWIs) into the migrated source code as comments. For more details on what an issue is look here.

Some general recommendations about handling these EWIs can be found here.
