While some like to like migrations can be partially performed using migration software, in most cases, a cloud transformation involves a great deal of manual work. The right software can automate some parts of the process and help make a migration more efficient, but the human element is a necessity—so ensure that you and your migration team have a firm understanding of the latest best practices related to cloud migrations.

For those who choose to engage a professional services firm to conduct their migration, identifying the right firm is key. Look for a firm that not only has a strong understanding of the types of automated solutions available, but also when they should and should not be employed. Additionally, a professional services migration partner should be able to architect your new environment, perform pertinent application installations and upgrades, conduct vulnerability scans to ensure your destination environment is secure, and execute load testing to guarantee that your cloud server will adequately handle expected traffic loads.

During

It is obviously essential that nothing is lost in the process of the migration. Other critical priorities to keep in mind during the migration and while deploying the environment include operational consistency (minimizing downtime), defining the scope of the migration, adhering to an established timeline, and understanding the technical and logistical requirements involved. Thorough testing of the workloads and applications that are being migrated is a key component of any migration. One thing to keep in mind is that this testing should be performed by the users themselves—the people that are going to be using these applications and accessing this information every day—and not technical staff who are not as intimately familiar with the granular details of the work.

In many cases, programmatic upgrades may be required. Be sure to have the right staff on hand to internally identify any incompatibilities or programmatic upgrades that will be required, or identify a migration services firm that brings these services to the table. Also, make sure you schedule in advance to have resources available when you need them. The last thing you want is to have two environments running concurrently for months due to poor planning and unforeseen issues.

After

Once the data and applications have been moved, extensive testing is required to make sure the new environment is fully functional. There is also plenty of general maintenance involved, including making sure that the software involved in tool chains and scalability is updated and maintained. Have a decommission plan in place: know when the new environment is secure, stable and recoverable and it is safe to decommission the old environment. Continual performance testing and load testing is key, especially if you are making numerous changes or have an application that is updated on a regular basis. Make sure you can handle not just the traffic you have today, but the traffic you may have in the future. Finally, once you are live in the new environment, you need to be performing proactive security scans at least quarterly to make sure you are secure.

Also understand that general maintenance practices should be observed after your migration is complete—specifically in regards to security. Even if vulnerability scans and hardening were conducted during your migration, these security processes should continue to be performed at least once every six months. If you possess the resources, however, it is a general best practice to execute them even more frequently.

Enterprise organizations undertake migrations for many reasons—the need to upgrade an OS or infrastructure, retire old equipment, or acquire higher performance and scalability capabilities. Regardless of the reason for your migration/transformation, taking the time to do it right is the key to minimizing expense and disruption—and avoiding having to do it again sooner than would normally be required.
