Recommended Migration

If currently using Cisco IOS Software Release 11.0(x), the recommended upgrade path is to Cisco IOS 11.2 or 12.0(x). If currently using Cisco IOS Software Release 11.0BT, the recommended upgrade path is to Cisco IOS 11.2, 11.2BC, or 12.0.

The migration path is the logical superseding software. The uniqueness of each network requires that customers verify support for hardware, features, and protocols prior to a massive network upgrade.
