Nordlicht Reisen GmbH, a fictional travel agency, has a file estate of about 40 TB in Hamburg (G-06): contracts, photos of the travel destinations and office shares. Lesson 2.4 decided where it belongs in Azure. This lesson chooses how it gets there: over the line, with a device sent by mail, or in both steps. Backing up this data is the subject of lesson 3.1.
Prior knowledge: You choose the target accounts and services (Blob Storage, Azure Files, tiers, immutability) in lesson 2.4 of this course; the framework of the migration, the assessment of the estate and the data paths (ExpressRoute, VPN, Data Box) are set by lessons 5.1 and 5.2; Azure Files and AzCopy as tools are shown in "AZ-104, lesson 2.4" and "2.5." None of that is repeated here. What is new is choosing the path by volume, bandwidth and deadlines.
The requirement
All numbers are assumptions of the exercise, not measured. G-01 to G-10 apply (lesson 0.2), especially G-06 and G-08. The target accounts from lesson 2.4: account A for contracts (immutable), account B for photos (tiers), and an account with Azure Files for the office shares.
