FIG 01 · Cloud Migration

Cloud migration services with a rollback plan for every move

Web apps, SaaS products, databases and sites moved to AWS, Azure or Google Cloud in planned waves, with rollback criteria written before day one and cost tuning after go-live, by the team that builds software.

FIG 02 · Quick answer

What are cloud migration services?

Cloud migration services move your applications, databases and files from on-premises servers or another cloud to AWS, Azure or Google Cloud. Elgrith assesses each workload, picks one of the 7 Rs, from rehost to refactor, migrates in planned waves with written rollback criteria, then tunes cost, security and performance after go-live.

FIG 03 · Why it matters

Moving to the cloud is easy. Paying for it well is not.

From Flexera’s 2026 State of the Cloud survey of 750+ IT leaders (its press release is in German; the figures below are our translation) and AWS’s own migration guidance.

FIG 04 · Strategy

The 7 Rs of cloud migration

AWS calls them the 7 Rs: seven ways to move an application to the cloud. Most estates use several. Here is what each one means, when it fits and how much work it takes.

The 7 Rs of cloud migration, compared
StrategyWhat it meansBest forEffort
RetireSwitch the application offApps nobody uses and duplicated toolsLowest
RetainKeep it where it is, for nowApps with a recent hardware refresh, licence lock-in or a compliance holdNone for now
Rehost (lift and shift)Move servers as they are to cloud virtual machinesFast data-centre exits and apps you can’t change yetLow

ReplatformSmall changes to use managed services, such as moving a database to Amazon RDS or Azure SQLApps that gain from managed databases, containers or autoscalingMedium
RefactorRe-architect the app for cloud-native servicesProducts that need scale or speed the current design can’t giveHighest

AWS’s own guidance says refactor “is not recommended for large migrations because it involves modernizing the application during the migration.” We usually move first, then modernize the parts that earn it.

FIG 05 · What you get

Our cloud migration services

Assessment, migration and the tuning after it, from one team that also builds and maintains software. We work on AWS, Azure and Google Cloud.

Cloud Migration · built in-house

01

Cloud readiness assessment

An inventory of servers, apps, databases and the dependencies between them, a total-cost-of-ownership comparison and a 7 Rs decision for every workload.

02

AWS cloud migration services

Moves to Amazon EC2, RDS and S3 using AWS Application Migration Service and Migration Hub, on a landing zone written in Terraform.

03

Azure cloud migration services

Moves with Azure Migrate to Azure VMs, Azure SQL, App Service or AKS, often the natural fit if you already run Microsoft 365 or SQL Server licences.

04

Google Cloud migration

Moves with Migrate to Virtual Machines to Compute Engine, Cloud SQL, Cloud Run or GKE, with BigQuery when your data team needs it.

05

Database and data migration

PostgreSQL, MySQL and SQL Server moved by dump-and-restore or live replication, with row counts and checksums validated before cutover.

06

Cloud-to-cloud and hosting moves

Shared hosting or a VPS to AWS, AWS to Vercel or Cloudflare for front ends, or one cloud to another, with DNS and SSL moved cleanly.

07

Containers and Kubernetes

Apps packaged in Docker and run on EKS, AKS, GKE or simpler managed container services when replatforming makes sense.

08

Cost and performance tuning

Rightsizing, reserved capacity, tagging, budgets and alerts after go-live, so the new bill matches the business case.

FIG 07 · Flagship build

Proof: a cloud-hosted AI platform we built

Kenerate AI is our flagship build, a cloud-hosted AI image and video studio we designed and engineered. It is not a migration project; it shows the platform engineering behind our migrations.

  • 200+ AI models behind one app, one login and one credit balance
  • 23+ studios and tools, with up to 4K output
  • MCP & CLI: use Kenerate inside Claude, ChatGPT, Cursor and 19+ AI apps
  • 1,000+ projects for 250+ clients since 2015
Kenerate AI section “Stop paying for fifteen AI apps”, comparing 15 separate apps with one studio, one login and one balance

FIG 08 · Cutover

Downtime, cutover and rollback

Microsoft’s Cloud Adoption Framework says migration methods fall into two categories: with downtime and with near-zero downtime. It also says to “always establish rollback criteria and procedures before initiating any migration.” We do both, in writing.

06principles

  • Migration with downtime

    A planned window: stop writes, copy, verify and switch. The simplest and cheapest route when a short outage is acceptable.

  • Near-zero-downtime migration

    Continuous replication of data and servers, then a short switch-over. More setup, very little interruption for your users.

  • Rollback criteria, written first

    The error rates, data checks and time limits that trigger a rollback, signed off with you before day one.

  • A rehearsed rollback path

    Rollback is tested in a dry run, so going back is a procedure, not a scramble.

  • Waves, not a big bang

    Workloads are grouped by dependency and risk and moved in waves, with the lowest-risk wave first.

  • Data validation

    Row counts, checksums and sample checks before and after cutover, so nothing is lost or changed in transit.

FIG 09 · FinOps

After the move: cost and performance

Flexera’s 2026 survey puts cloud cost management as the top challenge. Most providers stop at “migration done”. We tune the bill and the performance after go-live.

06principles

  • Rightsizing

    Instances, databases and storage sized to real usage once traffic has settled, not to the old servers.

  • Reserved capacity

    Savings plans or reserved instances for steady workloads, once usage is predictable.

  • Tagging and cost allocation

    Every resource tagged by product, team and environment, so you can see who spends what.

  • Budgets and alerts

    Budgets and anomaly alerts in your billing console, so surprises arrive as alerts, not invoices.

  • Monitoring and performance

    Dashboards, logs and alerts compared with the baselines we measured before the move.

  • Decommission the source

    Old servers and contracts switched off once the rollback window closes, so you stop paying twice.

FIG 10 · Measurement

What we report after go-live

Baselines are measured before the move, then compared at the check-ins agreed in your written scope, so you can see whether the migration paid off.

We don’t promise savings percentages before we have seen your bills and workloads. Targets are agreed with you after the assessment.

FIG 11 · Process · 7 steps

Assess first, then move in waves

A fixed written quote after the assessment, and rollback criteria signed off before the first workload moves.

  1. Step 01

    Assess

    Inventory, dependency mapping and cost comparison for every workload, with a 7 Rs decision for each. You get a written scope and a fixed quote.

  2. Step 02

    Plan the waves

    Workloads grouped into waves by dependency and risk, with the cutover method and rollback criteria for each wave written down.

  3. Step 03

    Prepare the landing zone

    Accounts, networking, identity, logging and budgets built as code in Terraform, in cloud accounts registered to your business.

  4. Step 04

    Migrate and test

    Each wave is copied or replicated, then tested end to end with your team before anything switches.

  5. Step 05

    Cut over

    The planned switch, with data validated before and after, and the rollback path ready if the criteria are hit.

  6. Step 06

    Optimize

    Rightsizing, reserved capacity, tagging and alerts once real traffic has settled on the new platform.

  7. Step 07

    Decommission the source

    Old servers, licences and hosting contracts retired once the rollback window has closed.
