Before the switch, review the gap between the recorded source snapshot and the intended cutoff:
• Agree who can keep editing, any editing pause, and which location remains authoritative
• Identify changes made after the snapshot and record their file/version references
• Have the authorized owner reconcile those changes through the approved migration process
• Repeat the affected content, access and link checks, then record the evidence for signoff
• Delay the switch if the late changes or required checks remain unresolved
