Server migration to Azure

First we check what can move as it is and what needs changes. Then we move it and stay with that environment.

Not every server is fit to move as it stands

A migration starts with a review of what sits in the server room. You need to know which machines and applications are ready to move straight away, which need changes and which are better left where they are. Azure Migrate does this assessment: it collects data on the machines, on the dependencies between them and on how much they actually consume.

This stage decides everything that follows. Without it a migration turns into moving whatever can be moved, and ends with a bill for compute nobody uses.

Animation: a scan of the server rack assesses each machine, and the result forms three groups of migration readiness

Three routes into Azure, each with a different cost

There are three approaches. Virtual machine migration moves whole servers with no changes to the applications. It is the simplest and fastest, but it carries the flaws of the old environment across with the servers, including capacity bought as a reserve.

Application migration means moving the applications themselves onto Azure services. It takes more work, but it brings the cost down and removes the operating system from your responsibilities. Data migration leaves the servers where they stand and moves only the data, for example with Azure Data Factory. The choice does not have to be the same across the company, because different systems can take different routes.

Animation: three migration routes lead from one server, to the whole machine, to the application alone and to the data alone

The target environment and access to it

Before anything moves, the target environment is built in Azure: virtual networks, subnets, storage and traffic rules in security groups. It is the same network design as in the server room, written as configuration instead of cabling.

Then comes access control and encryption. We agree who can connect and from where, and we encrypt data both on disk and while it travels. The cloud does not take that duty off the company, it moves it somewhere else.

You are not left alone after cutover

After the migration the environment has to be tested before the old servers are switched off. We check that the applications run, that performance holds and that nothing was left behind on the other side.

What remains is the backup, redundancy for a failure and monitoring that shows the state of the environment and its resource use. We run Azure day to day, so a migration does not end with handing over passwords.

FAQ

Before you ask

Will the company stop working during the migration?

It does not have to. Machines replicate into Azure in the background while the old servers keep running, and we schedule the cutover itself for the time that gets in the way least. The break covers the cutover, not the whole migration.

How long does a migration take?

It depends on the number of servers and on how many applications need changes. We give a date after the review of the environment, because anything earlier would be guesswork.

Do we still need an administrator after the migration?

Someone has to watch the backups, the updates, the access rights and the cost. You can do it yourselves or leave it to us, but moving to Azure does not remove that work.
