AFAIK, even if they live migrated the guests to a new host, they\u0027ll still be using the same instance path layout, since we don\u0027t rename/move storage on live migration.\n\nAt the very least this deserves a big warning in the release notes. The release note should tell people how to check whether they have any VMs using the old path layout, and some instructions on what todo to solve this.","commit_id":"8161e9e63f4567261e272bd2948ed2f898fd901d"}],"releasenotes/notes/instance-path-2efca507456d8a70.yaml":[{"author":{"_account_id":6849,"name":"Roman Podoliaka","email":"roman.podoliaka@gmail.com","username":"rpodolyaka"},"change_message_id":"2ff64f878df80a4b707871e4dc2a6a2001977bfd","unresolved":false,"context_lines":[{"line_number":1,"context_line":"---"},{"line_number":2,"context_line":"upgrade:"},{"line_number":3,"context_line":"  - Prior to Grizzly release default instance directory names were based on"},{"line_number":4,"context_line":"    instance.id field.
