SaaS (Software as a Service) is the future of businesses, and there are models which businesses can use for cloud-based SaaS Migration. To help you understand better, this blog will guide you on how you can migrate to SaaS.

The era of single-use software products is now gone, and businesses of all sizes are turning to Software-as-a-Service (SaaS) solutions to help them stay competitive. SaaS is a type of cloud computing that allows customers to access applications over the internet on a subscription basis. Unlike traditional software products, SaaS solutions are centrally hosted, managed, and maintained by the provider, freeing up enterprises to focus on their core business. 

The most significant example of how a company effectively used SaaS Migration is Adobe, which offered downloadable software packages but has now moved into a SaaS-based subscription model where users can pay a monthly or annual fee to access their product suite through an online platform. This has helped Adobe to improve consumer experience and offer them easy accessibility to their diverse range of software applications.

As this may sound quite lucrative, businesses should not miss any opportunity to migrate to SaaS as it can give them immense opportunities to save costs and gain competitive advantages.

Different Types of SaaS Migration Models

SaaS Migration Business Model is an approach to transitioning an organization’s applications and data to a cloud-based platform. It is a process that allows organizations to move their existing applications and data to a cloud-based SaaS provider while keeping their existing infrastructure and processes in place. This model is becoming increasingly popular as organizations look to reduce costs, improve scalability, and increase flexibility.

  1. Service-by-Service Migration Model

Service-by-Service SaaS Migration Model is a strategy for migrating software services from one platform to another, especially if you want to use microservices. It is a popular approach to migrating Software-as-a-Service (SaaS) applications. It can be used to move services from an on-premises environment to the cloud or from one cloud provider to another. This model is beneficial for organizations with many services and wants to move them in an organized, efficient manner. You must remember how you plan to divide your monolith system into multiple services while automating them separately.

For example, suppose an organization has a suite of SaaS applications hosted on an on-premises server. In that case, the Service-by-Service Migration Model can move each application to the cloud one at a time. In this, you should always prioritize the least important service first while keeping your system running. This allows the organization to test and validate the migration process for each application before moving on to the next, ensuring that the transition is smooth and successful. 

  1. Silo Lift and Shift SaaS Migration Model

Silo Lift and Shift SaaS Migration Model is a simple way to transition from on-premise infrastructure to the cloud. In this case, the application doesn’t need to be designed from scratch as it facilitates shifting the tech stack entirely to the cloud. This model is especially useful for companies that need to migrate their applications but don’t have the time or resources to complete the application’s re-architecture. 

The silo lift and shift model takes the existing application and its data, “lifting” it out of the current cloud platform and “shifting” it to the new platform. This process involves taking the application’s code, databases, and other components and moving them to the new platform.

  1. Parallel Migration Model

The migration process can become a challenge between existing and new applications, and it can slow down the process due to the complexity of interoperability. Parallel migration is a SaaS migration model that allows users to move their data and applications from the existing system to the new one in parallel. In this case, once the new model reaches its maturity, the existing tenants can be moved to new infrastructure to test the performance without impacting the existing one. It is a flexible model which offers agility to migrate data without downtime.

  1. Layered Migration Model

A layered migration model is a way of transferring data between different software applications using multiple layers.  This model is a structured approach to migrating to a SaaS platform. It breaks down the migration process into several distinct layers, each of which can be completed independently. This allows organizations to migrate their data and applications in a more organized and efficient manner. A layered migration model ensures data accuracy when migrating from one system to another, reducing the risk of data loss or corruption.


Data migration can be a cumbersome task for moving applications to the cloud. SaaS migration models can help organizations to stay up-to-date with the latest technology and provide them with the ability to scale their applications quickly. In conclusion, SaaS migration models offer organizations a cost-effective and efficient way to migrate their applications to the cloud, enabling them to take advantage of the cloud’s scalability, reliability, and security.
