• Install this release of DB Change Manager in a different directory than previous version. If DB Change Manager is installed in the same directory, the following error appears at application start up, "Unable to read workbench state. Workbench UI layout will be reset."

• If one of the conflicting versions is already installed on your machine, either change the default Workspace or delete all files from the Workspace directory. The Workspace directory location appears whenever you start DB Change Manager and can be redefined from this dialog box. If the same Workspace is indicated for the new version, as was indicated previously, the following error will result, "Cannot restore workbench layout."

• If DB Change Manager is already running, you can also modify the Workspace directory by choosing File > Switch Workspace > Other from the Main menu.

• The format in which schema comparisons are saved changed in 6.x. Use the import feature to import pre-6.0 schema comparison jobs.

• Beginning with version 17.0, DB Change Manager provides an upgrade process for moving jobs and other information from an existing DB Change Manager 4.0, 5.0, 5.1.x, 5.5.x or 5.6 installation. No upgrade process is required to move from 6.x installations to this release of DB Change Manager.
