• 8800-series phones of hardware version V15 or later need at least MPP firmware 11.3.3 and cannot downgrade to earlier MPP firmware; the 8821 and 8831 cannot be migrated. in context
• Cisco's phone migration article documents no procedure for returning a migrated phone to Unified CM, so reversal should be treated as unplanned work rather than a supported undo. inferred in context
• Unified CM phones must be on firmware 14.1 or later before Control Hub can migrate them to Webex Calling. in context
• Control Hub phone migration completes either automatically (wired phones pointed at a chosen TFTP server) or manually by uploading generated BAT files to Unified CM Bulk Administration. in context
