       let directory: NSURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: AppGroupID)! as NSURL
       let newStoreUrl = directory.appendingPathComponent("Model.sqlite")!
  
       var targetUrl : URL? = nil
       var needMigrate = false
       var needDeleteOld = false
  
  
       if FileManager.default.fileExists(atPath: oldStoreUrl.path){
          needMigrate = true
          targetUrl = oldStoreUrl
       }
       if FileManager.default.fileExists(atPath: newStoreUrl.path){
          needMigrate = false
          targetUrl = newStoreUrl
  
          if FileManager.default.fileExists(atPath: oldStoreUrl.path){
