i am not getting my portrait photos from my old iphone

If you're missing photos or videos in the Photos app - Apple Support

If you were not using iCloud photos to sync your photographs then they may still be stored on another device or as part of a backup. You can restore the backup ( https://support.apple.com/HT204184 ) to recover the photos but doing this will require erasing your device and restoring everything back to the time when you made that backup.
