Name the owners
Assign business and technical owners. Document who can approve access, update content, and handle support questions.
Design around findability
Organize libraries and navigation around how people look for information. Agree on naming and metadata before moving large amounts of content.
Review permissions deliberately
Group membership and access reviews should have clear responsibilities. Avoid treating a migration as an opportunity to copy every historical permission without review.
Leave a usable handoff
Provide a site map, permission model, publishing guidance, and training. The team should know how to maintain the site after delivery.
