Migration strain exposes partner capacity challenges

Migration has been treated as a technical exercise for years now. It’s seen as a task that must be worked through line by line, customer by customer, alongside the regular day job. That approach, however, is now starting to break. Rather than just the technology changing, it’s also the scale, pace, and commercial impact of getting it wrong.

Most partners understand the PSTN switch-off at a technical level, but the operational weight that accompanies it if often underestimated. Partner businesses are typically well-tuned, with sales and marketing generating demand, while delivery and support are built to meet that demand. There isn’t a bench of unused resource waiting to absorb a large-scale migration project.

So, when migration hits, something must give. Partners must either slow down new business, stretching support and risking the customer experience, or try to do both and put pressure across the entire operation.

That’s where the real challenge lies. It’s capacity, rather than capability. Forcing migration into a business that wasn’t designed for such a change becomes a needless distraction at the wrong time.

Managing migration as a series of individual tasks sounds optimal, but it quickly becomes complex. Most estates are multi-vendor, services sit outside of a partner’s control, and involves different technologies, contract and compliance requirements. It’s a messy reality.

The more successful partners start with understanding, rather than execution. They analyse the full customer base, segment effectively, and identify different migration plans that helps call out exceptions early. Might not be glamorous, but it’s integral to the process. When done right, everything that follows becomes easier. When done wrong, issues compound quickly.

Existing customer bases is one of the biggest migration risks that’s often overlooked. Many partners see legacy as stable, profitable and low touch. Margin is being generated without creating significant operational overhead, but when handled badly, migration can erode that. Handled well, margin is both protected and strengthened.

The goal isn’t just moving customers. It’s maintaining commercial value, keeping customers supported and compliant, and moving them onto technology that keeps them relevant long-term. At the end of the process, customers need to feel as if they’ve progressed, not been disrupted.

PSTN timelines are an obvious trigger, and price increases are accelerating urgency. But the bigger shift is happening in how partners think about technology choices. Increasingly, the question is where it will take customers over time.

In a subscription world, partners and end users only move as fast as the vendor they align to. That puts focus on things like R&D investment, security capability, AI development, and long-term viability. Simultaneously, partners are reassessing their installed base, asking whether their current technology is keeping up. Is it introducing risk, and do they want to keep building on it? Often, the answer is no.

That’s what’s driving broader, more strategic migration decisions, not just compliance-led ones.

There’s also a natural concern from partners about losing control of the customer relationship during migration. That doesn’t need to happen, because when done properly, the partner remains the face of the relationship. The migration capability sits behind them, adding capacity rather than replacing ownership.

That balance is critical. Maintaining trust, protecting the customer experience and enabling partner growth are all additional objectives besides completing the project.

If there’s one piece of advice, it’s simple. Spend more time at the start; analyse and understand the customer base in detail. Be clear on the end state and define how different segments will move. The work done upfront pays back many times over.

Never assume you must do it alone. Even bringing in external perspective at the planning stage can change the outcome significantly.

Migration is often framed as a problem to solve, rather than a decision about how a partner wants to grow. Handled reactively, it creates pressure across the business. Handled strategically, it protects the base, strengthens customer relationships, and creates space to keep winning new business.

That’s the difference.

If you’re working through what migration looks like across your base, it’s worth starting with a simple conversation. Compare approaches, sense check the plan and understand where the pressure points are likely to sit. That upfront clarity can make a meaningful difference to the outcome.
