Changing Storage-Manager Vendors

When you switch storage-manager vendors, the transition can be difficult. Ensure that the new data formats are identical, that a reversion utility is provided, or that you do not use new features that change the data formats. Differences usually occur in the following areas:

• The new storage manager might support different storage devices. If you also upgrade a storage device, make sure the old storage device is available until you successfully back up and restore on the new storage device.
• If you change physical connectivity, such as moving a storage device from a local connection to a network server, make sure the storage manager can still move the data across the network.
• If you use software compression or encryption, make sure all versions of the compression or encryption algorithms are available for restores.
• Ensure that the storage manager can send multiple data streams to storage devices. It also might use a different version of XBSA.

You can switch between certain storage managers more easily than others. For details, contact Technical Support or your vendor.
