Make sure to make a backup of your openings.

Hi Evan,
In the main menu, click on the "BACKUP" button and enter a filename "my_backup.crtdb". This file will be saved in your external memory (SD card) in the "/ CRT_Backups" folder.
Using a third-party file manager, copy the backup file to the cloud in your Google Drive (or dropbox).
Now, using your second device, from the main menu, click the "RESTORE" button and navigate to your Google Drive (or dropbox) to select your backup file. This will restore all of your openings on the second device. Be aware that when restoring a backup file, all current openings will be overwritten, so be sure to make a backup first as needed.
