upgrading third party application

Hello,

I wrote a 9700 applicationthat stores the data in the PersistentStore.

I would like to support an upgrade of the application that will not lose the application

setting and the data stored in the PersistentStore (if needed upgrade it)

Any ideas?

Thanks in advance,

Shana

Re: upgrading third party application

As long as your persistable classes do not change, users can upgrade your application without loss of its data.

 

If you are referring to the user upgrading their device OS, you'll need to implement Backup and Restore for your persistent classes.  Refer to the following link for more information.
