+**Notes:**
+
+- Projects (beta) is currently in public beta and subject to change.
+- If the project you are migrating contains more than 1200 items, open issues will be prioritized followed by open pull requests and then notes. Remaining space will be used for closed issues, merged pull requested, and closed pull requests. Items that cannot be migrated due to this limit will be moved to the archive. If the archive limit of 10,000 items is reached, additional items will not be migrated.
+- Note cards are converted to draft issues, and the contents are saved to the body of the draft issue. If information appears to be missing, make any hidden fields visible. For more information, see "[Showing and hiding fields](/issues/trying-out-the-new-projects-experience/customizing-your-project-views#showing-and-hiding-fields)."
+- Automation will not be migrated.
+- Triage, archive, and activity will not be migrated.
+- After migration, the new migrated project and old project will not be kept in sync.
