Start with Clearing Space on the iPhone:
There may just not be enough empty space. So, try emptying some more of it. Many system resources may be being used by unnecessary items. So, you need more internal storage space. Consider performing the following...
A. Clean TV and Music Libraries:
Remove all unneeded files from your TV and Music Libraries. Full-Movies take up 2-4GB typically, and a bunch of those would take up a load of storage, ideally. So, if you have any movies that are not needed, then delete them.

B. Clear Temporary Internet Files:
Clear your Temporary Internet Files(Cookies & Cache) of Safari:
Also...
C. Clear "Other":
Clear the storages named "Other". It basically contains unnecessary files such as caches that are used for system ease of use - all of which gather over time: How to Clear "Other" in your iPhone's Storage - Use Backup - User Tip
Once Cleaned...
Sync Through iCloud:
Sign in to the same Apple ID on the new iPhone, and then enable Photos in iCloud Settings on both iPhone. Once photos is synced, then all should presumably upload to iCloud, and be accessible to both iPhones. In the long run, all should be accessible, given they are associated to the same Apple ID.
I. On Both iPhones:
- Click: Settings
- Tap: your Name (top item)
- Tap: iCloud
- Tap: Photos (so that it is green)
II. Then, Check iCloud:
See if you can access particular items, through iCloud, directly. Go Here: https://www.icloud.com/photos
