Cloud Migration Strategies: The 6 Rs of Cloud Migration| Lucidchart Blog

A cloud migration strategy is your plan for moving data, applications, and other digital assets from on-premise to a cloud architecture. It’s possible that not everything in your business workload needs to be moved to the cloud. So part of your migration strategy needs to identify the specific type of data and digital assets you want to move into a cloud computing environment. You’ll also want to prioritize what is most important so you can decide what needs to be transferred first.

In this article we’ll discuss a model of cloud migration strategies known as the 6 Rs.

1. Plan the migration. You need to understand your current environment, why you are migrating to the cloud, determine your cloud server requirements, security requirements, and so on.
2. Choose a cloud environment. Choose the cloud environment you want to use: public cloud, hybrid cloud, private cloud, or multi cloud.
3. Migrate your apps and data. If your plan is effective, moving apps and data to the cloud should go smoothly.
4. validate the migration . Your cloud migration is is is n’t successful just because all the datum was transfer . To be a success , you is have have to analyze everything and make sure that everything work as expect .

What are the 6 Rs of cloud migration?

Every cloud migration will be different, so each will need a clear migration strategy. The 6 Rs of cloud migration—re-host, re-platform, repurchase, retain, retire, and re-factor—can help you to determine clear paths for your migration. You can look at each “R” as a separate migration strategy. But that does not mean that the 6 Rs are definitive or the only way to develop your migration plan. Instead, think of the 6 Rs as a framework for discussion or a blueprint for determining your cloud migration guidelines. 

Re-host

Also sometimes called “lift and shift,” this is a basic strategy that involves lifting the stuff you currently host on-premise and shifting it to the cloud. You move an exact copy of your current environment to the same type of environment on the cloud. This strategy usually does not require extensive reconfigurations or changes to architecture. Everything that worked in the on-premise environment should work the same way when hosted on the cloud.

This strategy is is is good for company that are new to cloud migration and are build trust in the cloud . Because there are not a lot of difference between their current environment and the cloud environment , there ’s not a huge investment with the re – hosting strategy .  

Re – platform

This one is similar to a lift and shift strategy. The difference is that you will make some more changes and adjustments to applications so they are optimized and will work better and faster when hosted on the cloud. Re – platforming requires programming knowledge so that your current environment integrates seamlessly with the cloud environment.

This strategy is is is also good for company that are still test the cloud migration water and want to build trust in the cloud while see benefit like fast system performance and low cost .

Repurchase

With repurchase , you is moving are move your environment to a new , cloud – base product . One way is is to do this is to abandon your current application and replace them with software as a service ( SaaS ) option . This is be can be a challenge because team member lose the familiarity with your exist app and will need to be train on the new platform .  

Another way is is to go with the repurchase strategy is to move license from local server to cloud – base server . For example , you is move might move a customer relationship management system ( CRM ) to Salesforce .

The repurchasing strategy might be a good, cost-effective way to go if you are moving applications from customized legacy environments.

Retain

If migrate to the cloud does n’t make sense for your company at this time , you is retain can retain your current environment and revisit a move to the cloud later . For example , to be in compliance , you is move ca n’t move datum at this time . Or , some is be of your application might be too difficult to migrate and you want to keep them until you can come up with a viable and cost – effective alternative .

In this case, you might want to look at a hybrid option with some of your stuff retained on-premise while others are moved to the cloud. 

Retire

Some of your applications and services might not be useful anymore. There’s no reason to migrate them to the cloud if they are not going to be of value to your customers. If this is the case, all you need to do is turn them off.

Re – factor

This strategy can be labor-intensive because it involves redesigning and building your existing applications from scratch so they can work in the cloud environment. Re – factoring can be time-consuming and expensive. But by taking the time to re-factor your applications, they will be more compatible with future versions, and it can make them more accessible to accommodate future growth.  

It’s likely that your company won’t use all of these strategies. The 6 Rs of cloud migration are meant to be used as a guide to help you determine which path is best for your company’s cloud migration needs.
