What are the types of cloud migration?

Three types of cloud migration include: full, partial, parallel. Let’s take a look at what each of these mean.

  1. Full migration refers to the type of on-premises to cloud migration. Traditionally, it’s the process of moving your existing physical IT infrastructure (applications, data, settings) to the cloud. The end result of this migration is the same infrastructure known and clear to your employees, but in the cloud. Small and medium-sized businesses usually opt for full migration as their IT systems are not as large as those that belong to enterprises. The execution typically takes a few days and faces minimal risks. The downside to this is that not all cloud features are available.
  2. Heritage migration transfers only a portion of IT systems and data to the cloud. This is a good way to test the cloud service and figure out if you really want to completely move your infrastructure. Usually, large companies use this approach.
  3. Parallel migration means you can use your existing system when migrating to the cloud. The peculiarity of this mode of migration is that it will be necessary to maintain both systems at the same time.
