Ensure that your Vibe data is backed up before you begin the upgrade process. For information about the data that needs to be backed up, see Backing Up Vibe Data
in the OpenText Vibe 4.0.8 Administration Guide.
Because of significant changes to the database schema, OpenText recommends that you use your database backup software to back up your Vibe database before upgrading to Vibe 4.0.5 or later.
