Software Image Migration Guide

Figure 1 displays Cisco IOS Software Release 12.2(37)EX functionality relative to the 12.2 and 12.2S releases. This diagram also identifies the recommended migration path for Cisco IOS Software Release 12.2(37)EX. Note that Release 12.2(37)EX is a special one-time "X" release with no planned maintenance releases. Thus, bugs that would have otherwise been fixed in a maintenance release will be fixed in the 12.2SE train and will be available in the 12.2(37)EXX release or a release based on 12.2SE. For more information about the Cisco IOS Software release process, refer to Product Bulletin No. 537.
