Application Migration
Businesses nowadays consider application migration as a preferable option to getting greater flexibility, scalability, and agility by transferring apps into the cloud. By moving software from a particular computing environment to another, the value of that software will be multiplied and businesses will be significantly benefitted.
Considering the time frame for successfully migrating an app without reengineering or re-architecting, it takes around four to eight months.
As far as the fundamental steps are concerned, we following the following sequence-
collection of migration prerequisite data ˃ planning ˃ designing ˃ updating app architecture ˃ mock migration ˃ testing of mock migration ˃ final migration ˃ final testing ˃ withdrawing of unwanted application parts ˃ support.
We incorporate a team of wide-ranging experts such as project managers, business analysts, cloud solution architects, DevOps, software and database engineers, and IT security professionals that will smoothen the process of app migration.
The cost of the migration process varies based on the size of the application. A small app requires a $50,000 investment, however for a medium-large app you ought to invest $200,000 to $ 500,000.

Sample Sequence of Application Migration Stages
Collection of Prerequisite for App Migration
Examine an app portfolio that carries information like solutions stack, app’s scalability, flexibility, tolerance level, and the server environment.
Evaluate both security risk and compliance risk of the app.
Determine app user access management and its readiness.
Know which part of the apps require migration on the basis of their dependencies, availability needs and business complexity level.
Planning
After gathering the prerequisites for app migration, we make a high-level plan to ensure smooth app migration.
Before this, an analysis will be done to invigilate the business processes so that all necessary functionality will be considered for migration.
Designing
Time frame: 1 to 2 months
Choose an appropriate target environment for app migration, whether cloud, on-premises or hybrid.
Choose a suitable approach (rehost, replatform, refactor, retain, repurchase for cloud migration/for enterprise app, retire or a combo of various approaches)
Select a cloud platform and suitable cloud services.
Considering solutions stack, conduct code assessment to find out the loophole and work on that.
Get a comprehensive idea of dependencies.
Select a specific time to execute the plan.
Updating App Architecture & Code (excluding purchased enterprise apps) & Data Migration
Time frame: depends on the depth of change (updating app design and code)
Time frame: 3 to 10 weeks (data migration)
Adjust app architecture and code keeping in mind the new environment, especially for legacy apps.
For cloud migration, update app design and code and get benefitted by the cloud services and its scalability.
Check data validity and authenticity and make data extracting, modifying and uploading.
Automate data migration.
Do trial data migration and later validate it.
Assessment of result.
Mock Migration & Testing
Time frame: 2 to 4 weeks
In order to lessen migration risk, set up a beta environment.
Test the migrated app’s functioning by utilizing test data and database.
Examine flexibility, infrastructure and scalability of app after updating production-equivalent test data.
Assessment of result.
Get away from the issues identified during mock migration.
Final Migration & Final Testing
Time frame: 3 to 6 weeks
Follow the similar format of mock migration.
Finalize and discuss on app’ downtime.
Establish a new production environment.
Make use of DevOps tools and processes.
Perform App Migration and migrate APIs.
Look over the changes and update configuration of the app.
Confirm that the migration process doesn’t affect the app’s functionality and business as well.
Perform App Migration and migrate APIs.
Put up monitoring tools.
Withdrawing of Unwanted Application Parts
Time frame: 2 to 4 weeks
Disable the old app or unwanted parts of the migrated app which will pose issues in future.
Support
Put up monitoring tools to access the functionality and performance of the migrated apps.
For the migrated app, we build and execute an operating cost optimization strategy.
Skills Required for an App Migration Project
Project Manager
A project manager manages everything beginning from the planning of app migration, assigning and supervising the tasks and their implementation, offering specified, quality is proven, and affordable project deliverables to the migration team, updating the stakeholders on the project’s progress communicating with vendors and cloud providers.
Cloud Solution Architect
A cloud solution architect is assigned the task of looking over the technical needs of the app to be migrated, designing a new cloud environment and drawing up its features and benefits after implementation, and selecting the migration approach and architecture for the new app.
Business Analyst
A business analyst analyzes business demands and goals, defines the scope of app migration and its requirements, smoothens the process of transition to the new environment.
Developer
A developer mainly deals with the coding tasks. They’re supposed to audit code for the app to be migrated, do recoding, if required, or bring changes in the app’s code. Configuration and customization can be done to a repurchased app, to meet business needs.
DevOps Engineer
A DevOps engineer entails an approach of infrastructure-as-code and automated deployments such as testing and CI/CD pipelines and optimizing orchestration. Also, they configure monitoring tools for performance, issue detection, and set alerts at the time of issue.
Software Engineer
A software engineer sets up sophisticated architecture patterns and apt cloud services to the app which will be migrated along with its refactorization.
Database Engineer
A database engineer’s job role is simple as they have to select a suitable database platform and implement data migration tools.
IT Security Specialist
An IT security specialist provides security recommendations at every stage of cloud migration and network system along with retrieving control mechanisms and management of the migrated app.
Sourcing Models for Application Migration
In-house team
Pros
- Full control over the app migration process.
- Ensure team productivity.
Cons
- To fill up the gap, you need to hire specialists who won’t be helpful otherwise after the migration process.
- The budget will be hampered if you hire.
- Suffer from a lot of burdens and lose focus on other core business affairs.
- Bear the pain of managerial and hiring efforts.
Partial or full outsourcing of technical resources
Pros
- The in-house team is aware of the current software environment and accesses the assets easily.
- The outsourced team will offer expert guidance on every matter related to app migration and fill up the gap if any.
Cons
- You’re supposed to bear the burden of partial/full team coordination, quality control, and risk management tasks.
Full migration process outsourcing
Pros
- Share the burden with a vendor that takes full responsibility.
- Fully established app migration frameworks.
Cons
- The higher risk involved as far as migration or modernization is concerned.
Cost of Application Migration to the Cloud
Moving the app to the cloud will cost you an amount (generally charged higher by other companies), but with us, that amount will be affordable and just.
Major migration cost factors
The key factors responsible for the major migration cost are:
Number of applications to be migrated.
Complexity involved in the app migration process.
Data involved.
App migration option- public, private and hybrid.
Life span & migration readiness of the app.
Availability demands.
Demand for code-level modification and high-level programming language.
Migration automation cost and extent.
Life span & migration readiness of the app.
Testing coverage for unit, system and performance.
Cloud services price.
Major post-migration cost factors
Infrastructure cost- app and its infrastructure support
Maintenance cost.
Training of IT support team.
