It’s been two years since I left Microsoft, and they finally decided to cancel my free employee Azure account. It was fun while it lasted, but now I have to move my data to a regular paid account. I looked through the FAQs and contacted support for the easiest way to do this, and unfortunately there is no officially recommended solution for moving storage accounts between different subscriptions.
I found some Windows-only tools that may have done the job, but I wanted a solution that would run on any platform. So I decided to write and share some quick NodeJS scripts: https://github.com/nabsul/migrate-azure-storage
npm run copy" to copy all blob and table data
npm run compare" to compare the data between the accounts
