Your Remediation Items checklist may include tasks to complete when your site is in SharePoint Online. In addition to any rebuilding of functionality after your site contents have been replicated in your new SharePoint Online environment, you should check that your contents and their metadata (e.g. Created, Created By, Modified By etc.) have moved successfully, by comparing them with the SharePoint 2010 source. This comparison should include actual content itself and the metadata associated with it.
Your SharePoint Online site is live as soon as migration is complete. Before you advise your site contributors and visitors your site is ready for use, be sure to review it to make sure it is working the way you expected.
Expect some final reminders from the Project Team to guide you through these last steps.
Post-Migration Message from the Project Team Confirms your migration status with a reminder to validate your site .
Final Project Team Message A final message that includes a message template for owners to copy/paste and send to their site contributors/visitors .
Owner Experience Survey We need your insight and feedback! Help us enhance the experience for owners in future migration waves.
