If you have both your old and new iPhones, transferring your data is very easy. The following process will ensure that you have a backup of your data, yet will make it easy to do the transfer.
Backup your Meter.db with iTunes File Sharing
The first step is back up our database, which is called Meter.db, using iTunes File Sharing. Here is a knowledge base article from Apple on using iTunes File Sharing to access data within apps.
What you are looking to do is to copy the Meter.db from our app on your old iPhone onto your desktop or laptop. That way, if other more automated ways fail, you could always install this database on your new iPhone.
Transfer all your data from old to new iPhone
Most people go with the approach of using Apple’s standard process to transfer their data to their new iPhone. You might not want to do this, but it is the easiest way to get all your data on your new iPhone.
Here is Apple’s knowledge base article on transferring data to a new phone.
The general idea is that every time you sync, you store all your app data into you iTunes on your computer. All you do in the process is restore it. When I got my new iPhone 4, and the process was smooth and easy.
If this is the method you use, then all your data should be transferred easily, and you do not need to use any other steps.
If you want to use iCloud, go to More > Settings > iCloud on your old iPhone, and then tap Save Now. Be sure to let the backup transfer before you shut off the old iPhone.
Then install our app on your new iPhone. If it was a fresh install and iCloud is on, then our app will prompt whether you want to restore from iCloud.
However, we recommend that you also be sure to use iTunes File Sharing to be doubly sure your data is backed up.
If something goes wrong, use your iTunes File Sharing backup of Meter.db
If the previous steps did not transfer your data, then use the App Store app to purchase our app again on you new iPhone (you won’t be charged if you use the same iTunes account). then use iTunes File Sharing to put the Meter.db you saved on your laptop or desktop into our app on your new iPhone, replacing the Meter.db already in the app.
