Abstract
In one aspect, a computer-implemented method for ensuring a source database (e.g., target space or index space) has correct version information before a migration includes executing, using at least one processor, instructions recorded on a computer-readable storage medium. The instructions include determining whether a table has been changed since a most recent alter of the table, performing an update on the table when it is determined that the table has not been changed since the most recent alter, and performing a rollback on the table after the update. The method may also include creating an image copy of the data in the source database and refreshing data in a target database with the image copy of the data in the source database. The method may also include automatically repairing the target database when the version information of the target does not correspond with the version information for the source.
