Automatic migration happens when a model is opened: as shown in Figure 2, if the system detects that an older version of the profile is applied, it will prompt you to perform the migration.

It also has a nice feature called automatic schema migration, which automatically modifies a database table based on differences JBoss finds with a newly deployed application.

The manual update is a required step in the migration project to address the missing features that automatic conversion can not fulfill. There are a few steps required.
