(Resolved) Restore V12 from V10 backups

In the fresh server I saw that frappe version and erpnext version aren’t the same. [image] then I run sudo bench switch-to-branch version-12 --upgrade and got both in version-12 I run this bench reload-doc Core Doctype milestone_tracker but I got this message /apps/frappe/frappe/core/doctype/milestone_tracker/milestone_tracker.json missing I dunno what else to do. Any one with a suggestion?
