Cloud migrations fail when you lift unknown servers into a new bill without knowing dependencies, identity, or how the warehouse scanner still talks to the old host. Planning is inventory and rehearsal, not a logo change.
The outcome you want is a cutover with a rollback, not a weekend of surprise latency.
Why OC firms migrate
Aging on-prem hardware in Irvine offices, landlords who will not let you keep a rack, hybrid staff who need Microsoft 365 everywhere, and cyber insurers who dislike unpatched Hyper-V hosts under a desk.
Planning sequence
Discover workloads, data gravity, and compliance constraints (HIPAA, PCI, customer DPAs).
Choose IaaS vs PaaS vs SaaS per workload—do not force everything into VMs.
Pilot a non-critical app; measure performance from Anaheim and remote homes.
Size VPN or ExpressRoute bandwidth before cutover day.
Write a cutover runbook with owners and a rollback.
Tag resources for cost allocation on day one so idle VMs do not multiply.
Common traps
Lift-and-shift forever with no optimization.
Ignoring identity: Conditional Access and MFA must be ready before the cut.
Leaving the old server online “just in case” without a decommission date.
Use the cloud migration playbook and our SMB migration practices for sequencing detail.
