Data migration ssp4 to ssp5

Just purchased SSP version 5. Been using SSP version 4 for years. Can I migrate my data? I have hundreds of log entries and equipment configurations

    Richard,

    Yes, you can use iTunes File Sharing to move your files from SkySafari 4 to SkySafari 5.  You can do a web search for "iTunes File Sharing" if you are not familiar with it.  Unfortunately, Apple doesn't let one app access the files of another so we can't automatically import them.

    Another tip... This wont help you migrate from 4 to 5... but 5 has a new feature that lets you store much of your data on the cloud drive.  You can store equipment lists, observing lists, and logs and if you have more than one device (e.g. an iPhone and also an iPad or Mac then the files are shared.  If you add objects to an observing list on one device, you'll see that list on the other devices.  If you add a piece of equipment on one device, you'll see in your equipment list on the other devices. etc.)    

    To enable it in Sky Safari 5, go into "Settings", scroll down to "Storage" and you can pick the cloud option you want (e.g. "iCloud").  You have to do this for each device.

    Thank you for the tips.  I have implemented both!

     A quick question: most of the time that I observe, I don't have a data connection.   Are the data files cached on the device for use offline, and then sync when I next get a data connection?

    was thinking about that to.   I tried to simulate by shutting off my wifi and leaving storage set to cloud.  Created a new observing list with no problem.   I do not have a second device yet but if you have one, give this a try to see if it gets synced.

    Yes - that's the nature of the cloud drives.  They're actually a local space on your devices... but the device will synchronize it to the cloud whenever it detects a change.  

    e.g. if you create a local file, the device will synchronize it to the cloud (so now the file is in two places... your device and the cloud).  Say you add another device and enable the cloud drive... any files in the cloud will be sync'd down to that new device (so now the files are in three places... your original device, the cloud, and your new device).  Say your new device modifies a file (although this works generically for any file using a cloud drive (not just Sky Safari)... let's say you add a new eyepiece to your equipment list using your new device).  The device will notice that the modification time for that device is now 'newer' than the same copy of the file in the cloud... so it will sync the changed file up to the cloud.  Then your original device will now notice (when it has a network connection) that the cloud has a newer copy of the file so it will sync it down.  (So now your updated file is in three places.)

    Basically you have copies of the files - they are always available even if you have no network connection... but if you do have a network connection, the system will sync the latest changes based on the notion that the modification and sync it to any device connected to that cloud drive.

    This works for Apple iCloud, it works for Google Drive, it works for Dropbox, etc.  They all pretty much do exactly the same thing.

    Your device also has a "cache" which does not sync.  Sky Safari has the ability to download the Digitized Sky Survey (high quality telescope images taken in ideal conditions) of any piece of sky you want (this feature may be version-specific... I have the Pro version).  So... you're trying to look at a faint fuzzy and wondering... what is that faint fuzzy supposed to look like?  What would it look like if I didn't have all this light pollution.  You can download that piece of sky to see the actual DSS image data for it.

    To do this:

    Select the object of interest.

    Tap "Info" to display the information panel on the object.

    Tap "More" (the three dots in the lower right corner of the "info" panel)

    Tap "Show DSS Image"

    Sky Safari will download the DSS image and display it.  That data goes into a local cache.  I believe that particular cache is NOT sync'd to the cloud.  

    Also, in the "Settings" -> "Storage" section, you can set the "DSS Cache Storage" size to choose how much space you're willing to let Sky Safari use for local copies of these images.
