Top 10 Cloud Migration Service Providers in 2026

Cloud systems have become a default solution for businesses of any size looking to upgrade technical capabilities and achieve increased sustainable revenue. Reliability, security, and scalability are the main benefits of moving to the cloud. Migration to a tailored cloud infrastructure requires a certain level of technical expertise that companies may not have in-house. This is when cloud migration service providers step in.

“I’ve seen this story repeat itself again and again. Many companies technically have in-house developers who could migrate their systems to the cloud. On paper, everything is possible. But in reality, those teams are exhausted – burnt out from constantly patching and maintaining legacy systems. Instead of innovating, they’re stuck keeping the lights on," Andrew Lychuk, co-founder of Corsac Technologies.

To make your move to the cloud easier in 2026, we’ve rounded up the top 10 cloud migration companies that specialize in transforming legacy systems.

1. Corsac Technologies

Corsac Technologies specializes in transitioning legacy systems to major cloud platforms, including AWS, Microsoft Azure, and Google Cloud. They carefully plan each step of the migration, from application and database migrations to a complete infrastructure transition. The Corsac team handles ongoing optimization and provides expert support post-launch, training your in-house developers for independent maintenance.

“I’ve seen this pattern over and over in the industry – vendors modernize a system and then lock the client into endless updates and maintenance contracts,” says Igor Omelianchuk, CEO of Corsac. “We take a different approach. Our engineers transfer knowledge to your in-house team so they can run and evolve the system independently. And if at any point you need our help, we’re always there, but you’re never dependent on us.”
