Hi Roshan, 1. Is it possible to migrate subscriptions with the applications? Further, > I guess existing tokens will be invalid once migration happened right? > Migrating subscriptions will be facilitated in the migration process. And we are not planning to migrate the tokens ATM so, existing tokens will be invalid.
2. would you still plan to provide a UI for the import-export tool? it > would be really nice if we can. > We are sorry to inform that we do not have a plan to provide a UI for import-export tool.
