I would like to ask that if I could back up to new iphone only contacts and SMS
No such thing occurs.
About iOS Backups. This covers what is included in a backup, it is all or nothing.
Backups have NEVER contained media or apps.
Restore the backup on the new device then select the apps and media desired to be synced to the device.
FYI, relying on a single device as storage of contacts is not smart. Contacts are designed to be synced to a supported application on the computer or a cloud service. Choosing not to use the device as designed is merely asking for problems.
