About the brand migration feature
The brand migration feature automatically replaces H3C or 3Com brand information with HP brand
information for an H3C or 3Com switch to migrate to an HP switch. This feature is now available for the
HP A5120 EI, and A5120 SI, A5500 EI, A5500 SI, A5800, A5820X switches. You can use these
switches to form heterogeneous multi-brand IRF fabrics with the H3C and 3Com switches in Table 1, and
replace the brand specific information for the H3C and 3Com switches. For the HP switch models
mapped to the H3C/3Com switch models, see “Appendix A H3C/3Com to HP switch model
mappings.”

This feature prevents the following problems that a master re-election would bring when you manage
your network with IMC:
• Device information changes, including the vendor name, device model, and device panels.
• Removal of performance indices and data. IMC would use the default monitor settings to monitor
the new master.
• Re-collection of information about cards and other hardware components.
• Topology recalculation and configuration re-deployment that would result from port numbering
differences between the old and new masters.
