Hey @Violet — no problem, happy to help here! So are you looking to archive your current account associated with the email firstname.lastname@example.org?
"if I start building tool before my accounts restored, and then my accounts get restored, and then will my built app still exist for my new organization?"
> Just to clarify, do you have an app you would like to move over to your new org? If so, you can export your apps by clicking the 3 dots in the top right corner of the app > Export to JSON. Then, you can import this JSON file by clicking Create new (home page) > Import an app.
One thing to look out for, your resources will not be automatically copied over. Its easiest to create the resources with the same naming convention in your new org, that way when you import your apps the resources should automatically reconnect. Hope this helps, let me know if you have any questions! :)\
