In this article, we’ll discuss:
- Why migration projects often disrupt business operations.
- What businesses commonly get wrong when planning migration.
- How to structure a phased, low-risk migration approach.
Migrating legacy services is now a necessity for all businesses. To be future-proof, they need future-ready services. But why do telecoms migration projects come with disruption and complexity?
Some businesses have an over-reliance on ‘big bang’ migrations, where all services are changed at once. Others suffer from a lack of operational planning, or a general failure to map all their critical services. Businesses shouldn’t be underestimating the process behind user adoption and change management either.
What’s clear to see is that poor planning and sequencing is the reason behind such disruption. While the PSTN switch-off is very much a technology-based change, it’s a lack of coordination and understanding that can create challenges.
Partners need to be ready to offer a phased, low-risk approach to migration to minimise the risks and challenges. By working with a vendor that has the right expertise and support, partners can focus on growing their own business and building relationships.
What do businesses often get wrong when migrating from legacy systems?
Even with the PSTN switch-off deadline approaching, some businesses still treat it as something to complete, rather than manage. If businesses have a large, multi-site estate, there needs to be more structure, coordination and control.
Missing that mindset means mistakes start appearing:
- Treating migration as an IT project pulls teams aways from running the business, which soon has an impact on CX and service delivery.
- A lack of clear rollback or contingency planning means small issues can turn into service disruption.
- Moving everything at once, instead of prioritising risk, starves businesses of the opportunity to learn and scale effectively.
- Ignoring dependencies across services can be damaging and will undo all the work done towards migrating.
- Not involving partners early enough inevitably causes rushed decisions and limiting visibility.
Partners need to be reminding their customers how complex migration can be. If handled reactively, migration only creates disruption. But when done properly, business continuity is assured across a more stable, future-ready estate.
What does a phased, low-risk migration look like?
The sheer scale behind migration can seem daunting. If partners can offer a clear framework, then businesses won’t have to feel like disruption is round the corner.
First, it’s integral to assess and segment the estate. Identify critical and non-critical services, while also prioritising sites, users and workloads. Understanding what services are currently in use helps to shift the focus to completing the low-risk migrations first.
Controlled pilot deployments can also help set the pace. Testing in smaller environments allows teams to better understand the processes behind migrating. Performance, usability and the workflows themselves can be properly validated.
Rollout would need to be phased. Migration can be based around location, function or even service type. There’s no need for businesses to pursue an organisation-wide change and having parallel systems in effect stops any risk of operational disruption.
Running these parallel systems fits in with the importance of business continuity itself. Rollback plans and fallback options create a critical safety net that can support coverage during transition.
Again, a phased, controlled migration is the ideal option. It allows businesses to reduce risk and maintain continuity as the move to future-proof solutions begins.
What role does a partner play in maintaining operational continuity?
Partners need to be ready to support a smooth migration. They need to be equipped with the tooling and experience needed to support change at scale.
Having the ability to manage multi-site, complex environments build the foundations needed for a phased approach. Deeper knowledge of the dependencies between services helps uncover any gaps and minimise the risk of disruption.
Ongoing support before, during, and after migration is also vital. There’ll always be questions to answer, and support must be readily available. Only then can migration continue at pace.
At the same time, there need to be clear guidelines in place that further minimise the risk of disruption. Monitoring real-time service performance, internal communication plans, and relevant training all helps to reduce the potential for service disruption.
Partners will need to look towards providers with a channel-first model and the track record of managing migrations at scale.
Why is migration planning critical ahead of the PSTN switch-off?
A fixed deadline will be driving urgent migration activity. However, if businesses choose to rush deployment, then only disruption will follow. If partners have the right level of support in place, their customers won’t be tempted to take such an action.
Having a structured, phased plan avoids any damaging business impact. A programme like Edge Migrate is ideal in the sense that Gamma takes responsibility for migration execution. Taking ownership of moving customer based safely means partners can focus on growing their own business.
There is a critical need to prepare for the switch-off, but it’s one that doesn’t require rushed decisions. Change needs to be phased, and both partners and businesses need to stay in control.
Quick Answers: How to Approach Migration Without Disrupting Day-to-Day Operations
What is a phased migration approach?
A phased migration moves systems in stages rather than all at once, reducing risk and allowing issues to be resolved before full rollout.
How do you migrate without downtime?
By running parallel systems, scheduling carefully, and using staged deployment with rollback options, the risk of downtime during migration can be minimised.
How long does a telecoms migration take?
It varies depending on scale, complexity, and number of sites. Phased approaches typically reduce risk compared to single cutovers.
What should businesses prioritise during migration?
The main priorities are operational continuity, user experience, and service reliability. It should never be down to technological execution alone.
Why use a partner for migration projects?
Partners bring proven frameworks, tooling, and experience managing large-scale transitions across multiple sites. When backed by the right framework, migrating becomes a smooth, easy-to-follow process.
