Hybrid to Hybrid Migration approach

I'm consolidating multiple AD domains into single domain and have to migrate AD users from all the domains into the target domain. All the domain users are currently synching to single Azure AD tenant and same tenant is going to be used.

The target on-prem domain is already created but I'm facing challenge moving users with UPN suffix to target domain users using QOD (Quest on-demand) because the UPN is already present in the existing environment and have forest trust with target domain which creates conflicts to it.

Is there any way or better approach that you can suggest overcoming the UPN suffix conflict issue?

    Hello there,

    Hybrid to Hybrid migration refers to migrating resources and workloads between two hybrid cloud environments, typically involving an on-premises environment and a cloud environment. Here are the key steps involved in a Hybrid to Hybrid migration approach:

    Assess Your Environment: Begin by assessing your current on-premises and cloud environments. Identify the resources, applications, and dependencies that need to be migrated. Understand the interconnections and potential challenges that may arise during the migration process.

    Design the Target Environment: Determine the target hybrid cloud environment where you plan to migrate your resources. This could be another hybrid environment or a different cloud provider. Consider the infrastructure, services, and connectivity options required in the target environment to ensure compatibility and functionality.

    Plan the Migration Strategy: Develop a detailed migration strategy that outlines the sequencing, timeline, and steps for migrating each component or workload. Identify any dependencies, potential downtime, and required testing or validation processes.

    Establish Connectivity: Set up the necessary network connectivity between the source and target environments. This typically involves configuring virtual private networks (VPNs), hybrid networking solutions, or direct interconnects to establish secure and reliable communication channels.

    Replicate and Migrate Data: Replicate or transfer your data from the source to the target environment. This could involve using tools like Azure Site Recovery or AWS Database Migration Service, depending on the platforms involved. Ensure data integrity, consistency, and minimal downtime during the migration process.
