What is AWS migration consulting?
AWS migration consulting helps organizations move workloads from on-premises data centers or other clouds to Amazon Web Services. Migration partners provide assessment, planning, execution, and optimization services — from simple lift-and-shift to full application modernization.
The best AWS migration partners hold the AWS Migration Competency designation, which requires validated customer success and technical proficiency reviewed by AWS. They typically use the AWS Migration Hub, Application Discovery Service, and AWS Server Migration Service alongside proprietary tooling.

Frequently asked questions
How much does AWS cloud migration consulting cost? +
Typical costs: Discovery assessments $25K-$75K, mid-size migrations (50-200 workloads) $200K-$500K, enterprise migrations (500+ workloads) $1M-$5M+. Hourly rates range from $150-$350 depending on partner tier. Budget 15-20% of total migration cost for consulting.
How long does an AWS migration project take? +
Timelines vary by complexity: Simple lift-and-shift takes 2-4 months, re-platforming 4-8 months, and full application modernization 8-18+ months. Discovery and planning typically adds 4-8 weeks upfront. Most partners recommend a phased approach with pilot migrations first.
What's the difference between lift-and-shift and re-platforming? +
Lift-and-shift (rehosting) moves workloads to AWS with minimal changes — fastest and cheapest but doesn't optimize for cloud. Re-platforming makes targeted modifications (e.g., switching to RDS instead of self-managed databases) for better cloud-native benefits. Re-platforming typically costs 30-50% more but delivers better long-term ROI.
Do I need an AWS Advanced Migration Competency partner? +
AWS Migration Competency partners have validated migration experience through AWS audits. For enterprise migrations (100+ workloads), this validation matters — it means proven methodologies and tooling. For smaller projects, any experienced AWS partner can deliver well.
