Frequently Asked Question

1. How long does a typical cloud migration take?

image

The timeline depends on the size and complexity of your infrastructure. For small to mid-sized businesses, most migrations take between 4 to 12 weeks. We provide a full assessment and roadmap before starting, so you’ll have a clear picture of what to expect.

2. Will there be any downtime during migration?

image

We aim to keep disruption to an absolute minimum. By using phased migration waves, off-peak scheduling, and testing environments, we ensure critical systems stay online while your data and apps are moved.

3. Is cloud migration secure?

image

Yes, especially with AWS. We use industry, leading security best practices, including encryption, IAM (Identity Access Management), network protection, and compliance controls. Your data is safe during and after the move.

4. Can we get funding or support for our migration?

image

Yes. As an AWS Migration Competency Partner, D55 can help you access the AWS Migration Acceleration Program (MAP), which offers funded assessments, migration support, and credits to reduce costs.

What our Clients Say

“While we led the initial business scoping and discussions with key stakeholders, it was a very smooth process working the D55 team to expand on this vision. The D55 team took ownership of building the solution and worked closely with us throughout the process. The quality of the work, combined with the excellent support during the handover, is exactly what we value in a partner.”

Andrew Thomas
CTO
Amber

" D55 enabled us to migrate from on-premise to a cloud-based solution, resulting in monthly cost savings of about 40%. Cloud-based systems give us a high level of resiliency and an unlimited capacity to scale. We’ve really put in place the foundations for later phases of work and further cost reduction as we scale. It was a partnership as opposed to a service - we work well together. "
