Will there be downtime during the migration?

Some downtime may be required during an Azure migration, but the amount depends on the migration strategy. Many organisations use phased or hybrid approaches that allow workloads to run on-premises and in Azure, minimising disruption.  
 
With the right planning, tools such as Azure Migrate and replication technologies can help achieve near-zero downtime for critical applications. As your migration partner, we will schedule any necessary cutover activities during off-peak hours to reduce business impact.
