SD-WAN Migration Steps to Follow

SD-WAN Migration Steps to Follow

Enterprise Networking Mag | Friday, April 02, 2021

Many software-defined implementations can only build pathways for public cloud services through a local Internet breakout, others through hub-style breakouts.

FREMONT, CA: SD-WAN distribution options allow companies to distribute either as physical equipment or applications efficiently to branch offices and remote locations. Until initiating the migration process, leadership will need to collaborate with their IT workers and pursue these ten steps to ensure seamless network transitions:

1. SD-WAN Preparedness

Determine which applications need the most throughput on the network and which of them would be given priority. This aspect includes traffic flows and trends, any cloud platforms being used, SaaS frameworks, and how to bring them all together to a unified model.

2. Evaluate Access Types

Not all access forms are equivalent. Simply chaining different links together would not create an effective network. One will need their teams to determine the access lines' consistency and capacities and ensure that the organization's standards are fulfilled.

3. Assess How the SD-WAN can be Incorporated with the Existing Network

SD-WANs do not generally protect the whole network in terms of features. Think about how to incorporate the SD-WAN into the network infrastructure. This feature will help firms analyze the use of protocol and program while offering grounded knowledge of bandwidth and protocol.

4. Figure Out How SD-WAN is Going to Mesh with the Cloud Plan

Validate that the SD-WAN can operate with the clouds chosen. Many software-defined implementations can only build pathways for public cloud services through a local Internet breakout, others through hub-style breakouts. Some solutions cannot be entirely configured for efficiency or latency. Besides, only a small range of cloud services can be supported.

5. Mapping Connectivity Flows

It is crucial to find out how the links flow within the network to customize SD-WAN policies. This instance means that the whole application is equally allocated based on certain policies. Be clear about the bandwidth, routing, and performance requirements for the applications.

6. Holding Best Practice and Security Procedures Up To Date

Using this opportunity to monitor software against existing and potential enforcement or organizational security measures during the implementation's design and review component. One can exploit the capabilities of the public internet by using SD-WAN. Around the same time, not getting the appropriate mechanisms to use it will expose the network to various cyber-attacks.

7. Try Conducting a Pilot Test When Preparing the Migration

Launching a pilot test for the network gives businesses the chance to hammer out any possible problems or vulnerabilities that might occur. Determine if the network architecture uses the right access forms for the network and supports the applications' goals.

8. Site Priority and Migration Applications

Prioritize apps and places that would most benefit from the transition to the SD architecture. Firms will need to worry about prominent positions within the network as well as where apps are hosted. This instance will give enterprises a clearer understanding of how to build the migration strategy.

9. Track the Network Throughout the Rollout Phase

Validating and testing the need for a workaround to see how the network works under stress. One should also track remote site traffic and leverage both private and public links in active mode. Ensure that the most critical traffic moves along the most secure roads within the WAN, while low-priority traffic uses cost-effective routes.

10.  Effective Control of Network

Use the data from the SD-WAN monitoring systems to provide maximum visibility to the application and WAN output.
