#1 Requirements Gathering

The initial phase of the gathering starts with analyzing applications. Define app migration needs and requirements that give value to your business. Discuss the business goals and determine the application migration strategy. You should have the answers to how migration will fulfill customer needs, what would be significant, and what would be the total cost of the project. Understand the overall risk with the existing software applications and evaluate the project possibilities before starting the migration project.

Selecting the Migration Team and Methodology

Defining the scope

Outlining the goals

Assess the current systems

Evaluate the project possibilities

Review the scope and goals

Outline the process

Choose the points of contact

#2 Assessing the Environment

You may want to consider the assessment of the entire process before taking it up to the new cloud environment. Choose the right hardware and platform for app development process. Overcome the networking issues, and assess the maintenance process post-development. A thorough assessment before the development will ensure successful adoption and improve productivity and efficiency.

Evaluate the systems

Analyze the entire process

Hardware and platform analysis

Software assessment

App development process

Maintenance and update

Network issues and bottlenecks

User interface updates needed

#3 Application Functionality Review

To check the functionality of an application, you need to have knowledge of the workflow. Plan the workflow with the assistance of an app migration company or developers who understand the user flows. Get a detailed view of the application to decide on the source code. This will ensure that the code used for the application migration project is as per the business requirements.

Detailed view of the application

Knowing the user flows, and workflows

Source code analysis

Business logic analysis

Usage metrics

#4 Architecture Analysis

Focus on defining the architecture techniques to use in the application migration process. It is the evaluation of how a proposed architecture is suitable for the business requirements. Architecture analysis is the backbone of the project. A set of technologies, operating systems, servers, and models based on the industry and business needs will enhance the development of the application. prepare documentation of the architecture analysis for better vision.

Security analysis procedures, policies, and restrictions

Control versions, processes, and development environment

Server, OS

Deployment processes in place

Operations and usage needs- bandwidth, memory


#5 Migration Resource Checklist

If you want to migrate your application to a new environment, you should follow the application migration checklist to ensure you have not missed out on any steps. Identify if you want to migrate your existing application or remove the app as a whole. Ensure that migrating will remove all the bugs and errors that you are facing with the existing application.

Timelines defined

Resources (Available and Needed)


Problems needed to be solved

Alternative migration possibilities

Release dates for the different phases

#6 Technical Requirement

Now that you have completed the architecture analysis, decide on the technical requirements for application modernization. If you need app migration, customize the app with database migration without any technical hitches. Partner with the best app development company to get skilled developers who have a wide range of experience in app migration.

Documentation standards

Technical – tools, platforms

Coding best practices

Problems needed to be solved

Architecture requirements

#7 Test Planning

Without testing, launching any application is impossible. Testing the app will help you with reducing operational and maintenance costs, eliminate the risk in the business, enhance the application performance, and enhance technical support. Before migration, the testing team should create on-premise data and load it on the cloud to ensure it the working. Get real users to test the application and identify errors.

Test strategy

Test case development

QA planning

QA resource availability

Test case methodology

Testing documentation

Tools and procedures

Possible outcomes

#8 Compliances

Check the security and compliance part of modernizing the application. Ensure to check the regulatory requirements are met. Migrating an app should meet all the security concerns like VPN, firewall, or database security.

Regulatory requirements

Compliance standards

Security policies

#9 Accessibility

Moving your application to another platform can impact the performance if you are using the same data. Use strategies like offline copy migration, and replace data to avoid downtime. Master migration is a complex strategy to provide accessibility to the data. Documents with detailed commitments between the customers and app service providers will create and manage the services with ease.

Uptime standards

Service level agreements

5 Strategies for Application Migration

Read the following to know more about strategies to follow during application migration. There are 5Rs to follow that will help you plan better if you want to shift applications to the cloud.

  1. Re-host

    In simple terms, this is copy-pasting the existing setup of the application to the cloud. This is also cost-efficient as you do not have to deal with operational or infrastructural costs.

  2. Re-architect

    If you want to boost agility, re-architect your existing applications and upgrade. It is nothing but transforming an application into a native cloud environment.

  3. Revise

    Revised architect is the strategy to modify the code before migrating applications. This is a critical part that involves technicalities. You will need the help of a technical in-house team but it is a time-consuming process.

  4. Rebuild

    Rebuilding an application from scratch is another strategy for application modernization. You should consider this strategy only when the application does not meet the changing needs of the business objectives.

  5. Replace

    This strategy discards an application if it does not suit the cloud environment. Use third-party applications to prevent loss of data due to replacing the application in a new environment.
