Configuration Migration for Transparent Mode—In 8.4, all transparent mode interfaces now belong to a bridge group. When you upgrade to 8.4, the existing two interfaces are placed in bridge group 1, and the management IP address is assigned to the Bridge Group Virtual Interface (BVI). The functionality remains the same when using one bridge group. You can now take advantage of the bridge group feature to configure up to four interfaces per bridge group and to create up to eight bridge groups in single mode or per context.
In 8.3 and earlier, as an unsupported configuration, you could configure a management interface without an IP address, and you could access the interface using the device management address.
In 8.4, the device management address is assigned to the BVI, and the management interface is no longer accessible using that IP address; the management interface requires its own IP address.
You can upgrade from any previous release directly to 8.4. If you are upgrading from a pre-8.3 release, see the Cisco ASA 5500 Migration Guide for Version 8.3 for important information about
