Transfer data & apps to a new device after skipping iCloud transfer

If you have already set up your device, then...

You can still transfer these data.

• Photos & Videos --> Turn on iCloud Photos on old iPhone. Once synced use the same Apple ID on the new device. That's it.
• Contacts --> Contacts are not stored on an iPhone nor on SIM, they are synced to  Google, iCloud, AOL, Exchange, Outlook, Yahoo or any Other. Upload all your contacts to any of the above email client server.
• Any Specific Files --> Upload to Cloud Drives (iCloud Drive, Google Drive, OneDrive, DropBox, Flickr, box, AmazonDrive, Adobe Creative Cloud and Use Files app on iPhone
• Apps --> In any way they have to be re-downloaded using the App Store. Use the same Apple ID that you had used on the old dev device and see the purchased and Not in Device section in the App Store.
