I think it's cleaner to use a short > CGM prefix for the related uAPIs, so they're easy to identify as a group. Using an abbreviation like CGM or MIG or HW has a problem where it's hard to decipher for anybody not familiar with the live migration. So my vote is currently on using Peter's suggestion for CONFIDENTIAL prefix. Regards, Tony
