How to implement the restructuring of your WAN in a risk-minimized & cost-efficient manner through smart migration
Digitalization and the increased use of cloud services require higher bandwidths. This usually results in a restructuring of the company network, as the existing network cannot keep pace with the new requirements. The WAN is often migrated according to the "big bang principle". However, this harbors numerous risks. In addition, business operations can be impaired under certain circumstances. A "smart" migration minimizes operational risks, costs and effort.
Big bang migration
In a big bang migration, all existing connections are usually completely replaced by new lines. Although these are equivalent - with the same bandwidths, SLAs and with the same carrier - they require the allocation and setup of new IP addresses and adjustments to the local IT infrastructure. This in turn entails costs and operational risks.
From a certain size, all data networks also have lines with different, non-harmonized contract terms, so that a migration can lead to considerable double or replacement costs if the restructuring of the WAN is accompanied by a change of service provider.
A big bang migration therefore harbors additional risks and disadvantages:
- High one-off costs for setting up the new connections
- Double line costs during parallel construction and for remaining contract terms
- High IT resources required for the conversions
- Long project times with at least two parallel providers
- Uncertainties regarding the timing of the changeover due to delays or unexpected problems
- Malfunctions due to malfunctions during installation
- unknown service processes of the new, local carrier and line quality
- "Friction losses" due to the transition and change of contact persons and responsibilities, or disputes over responsibilities between the old and new service provider
- Coordination efforts and time coordination with many project participants
- High complexity of the overall project
Migration can also be smart - risk-minimized and cost-efficient.
Smart migration aims to minimize operational risks and reduce time expenditure.
Smart migration makes it possible to replace connections at a commercially favorable time, depending on the data network structure. This almost completely avoids operating risks without neglecting economic aspects and quality parameters.
The availability and performance of the entire network can be achieved through the targeted development of redundancies and quality-improving measures.
If quality deficiencies are identified on existing WAN lines from the previous provider, they can be brought forward in the migration process in order to achieve the desired performance and stability more quickly.
Smart migration also offers further benefits and advantages:
- Reducing the complexity of the IT infrastructure by integrating several network components in a virtual platform.
- Improvement of the user experience through the use of innovative routing algorithms.
- Increasing the level of security through greater transparency, especially with regard to new services and applications
- Scalability and flexibility for the connection and operation of additional locations and own lines
- Security through encryption of all data traffic
- Real redundancy through multi-carrier strategy
- Active use of all existing lines after redesign on an SD-WAN basis
The resulting added value is obvious.
Added value:
- Minimization of costs, expenses and operating risks
- Shortening the project duration
- Flexibility in terms of time by separating the transfer of responsibility from the migration process
- Faster achievement of cost and quality benefits
- single, overall responsible partner from the beginning
