Hi!
Yes, you can backup them using "Settings > Display and Use > Maintenance > Export settings > Google Drive" and import them on your new phone using "Settings > Display and Use > Maintenance > Import settings > Google Drive".
Another option is to copy CalenGoo's whole database, e.g. by using the backup under "Settings > Backups > Automatic backups" and using the function to upload the backups to Google Drive.
You can find further information and other options here:
Please don't hesitate to contact me again if you have further questions!
Kind regards
