Automatic Data Migration Data migration is automatic. Automatic data migration means that when you migrate from one database server to another, you do not need to use any data migration tools to move the data. The data migrates automatically from the source database server to the target database server after you bring up the target database server. For example, data migration between Dynamic Server 7.3x and Workgroup Edition 7.3x is automatic if the database servers use the same operating system. Data migration can also be automatic when you move between different versions of a database server in the same operating system. 2-8 IBM Informix Migration Guide
