Here’s a checklist of things you should do to move all your data when you change devices:

1. on your old device, make sure MyTrails is connected to your account, so your purchases, if any, will be available on your new device
2. make a backup of MyTrails’ state on your old device
   1. if you have rooted your device, you can use Titanium Backup or a similar tool
   2. if you have not rooted your device or are not sure what “rooted” means, you can use a tool such as MyBackup (you can install it from MyTrails > Preferences > About) or Helium
   3. if you can’t make a backup, at least export your waypoints from MyTrails into a GPX, by using the export global waypoints hidden option
3. unless you keep all your recorded tracks in Dropbox, make a copy of your recorded tracks on your computer
4. if you have offline maps, you can copy them to your computer as well
5. on your new device, install MyTrails (you don’t need to install the MyTrails Pro License application unless you haven’t connected MyTrails to your account in step 1)
6. if you made a backup in step 2, restore it on the new device
7. make sure MyTrails on the new device is connected to your account
8. check that your recorded tracks are still available (if not, copy them from your computer to the new device, and load them into MyTrails)
9. make sure your offline maps are still available (if not, first check the location for offline maps in MyTrails > Preferences > Other, then copy them from your computer to that location and restart MyTrails)
10. check that your global waypoints are still available (if not, load the exported global_waypoints.gpx; unfortunately the waypoints will no longer be global, but will remain associated with that track, which you should leave checked)
