Currently, I am using BOX to sync the database between iPhone & iPad, support for which, I believe, will be discontinued towards November end.
Is iCloud the way to go once Box support is discontinued? What steps do I take to safely/ smoothly facilitate the transfer of all my data from one sync location to another?
iCloud is only one option, additional ones are e.g. Dropbox or WebDAV-compatible cloud services like CloudMe. Or if you don’t need a cloud at all, then a NAS (e.g. Synology) or Bonjour are also possible.
