With Connect end of support starting on 31 January 2027, I ported a small open-source Connect app to Forge from start to finish, to see what a real migration involves. The app is samid737/jira-checklist-plugin : one issue panel for checklists, running on Express, atlassian-connect-express , SQLite and jQuery UI.
