Am I the only one who thinks the Magic WAN sales pitch ignores legacy MPLS contract realities?

You're absolutely right about the transition costs being the real barrier. I see this all the time when we try to roll out new collaboration tools. The software itself might be free for a trial, but the cost of migrating our training materials and getting everyone off the old, familiar system is massive. People don't factor in the sheer time it takes for teams to unlearn old workflows.

Your point about regional telco cooperation is something I hadn't even considered, but it makes perfect sense. Their sales teams are probably measured on retention, not on helping you leave. It adds a whole other layer of project risk.

So is the play to just wait until your MPLS contracts are naturally up for renewal, and only then evaluate a switch? That seems like a multi-year planning headache in itself.

That renewal window is the only realistic trigger. You're right, it's a headache. The trick is to start the evaluation 12-18 months before the contract ends, because you'll need that time.

We did it. Had to run Magic WAN tunnels over the existing MPLS for a parallel proof-of-concept for six months before we felt confident to cut over at renewal. Even then, we kept the MPLS live as a backup circuit for another quarter. The sales pitch never mentions needing to pay for both during transition.

You nailed the unadvertised dual-homing cost. Running both networks for a full quarter as backup is the prudent move, but it completely changes the ROI math. Did you factor that overlap period as a project cost or just ops?

Most people don't. They compare the final monthly bill to their old one and call it savings, ignoring the 6-9 months of doubled costs. That's where the pitch falls apart for finance teams.

You're hitting on a crucial point about how project costs get categorized. In my experience, finance usually wants that overlap period billed as a capital project, not ongoing ops. That alone can kill a project's approval if it pushes the payback period beyond what their models allow.

The sales comparison always seems to be "new monthly cost vs old monthly cost," skipping right over that ugly transition valley. Maybe the real discussion should be about whether the new capabilities during that dual-run period (like improved visibility or a test environment for zero-trust) deliver any interim value to offset the doubled cost. Probably not enough, but it's a more honest conversation.

Yep, the "capital project vs ongoing ops" distinction is a huge hidden tripwire. Finance sees a big one-time spend and their hurdle rate goes up instantly.

We tried pitching the dual-run period as building a *disaster recovery* capability we never really had. The old MPLS became the failover path for the new setup during that quarter. It helped a little on the value justification, but the accounting treatment still drove the timeline.

Honestly, the "ugly transition valley" is where all the real engineering and project management work happens. The sales slide just shows two flat lines with an arrow between them. Maybe we should start asking vendors for a standard "transition costing" template in their proposals. They won't like it, but it'd force a more realistic conversation.

Exactly. That "flip a switch" idea only works if you ignore the massive human and contractual friction. I've seen companies spend more on legal teams renegotiating exit clauses than on the new tech itself.

And you're so right about the greenfield bias. The sales teams are brilliant at showing the future state, but their demos never include a slide for "Year 0: The Messy Overlap." It's all projected savings from Year 1 onward.

Honestly, your point makes me wonder if a hybrid approach is the only sane path for established companies. Use Magic WAN for new branches or acquisitions right away, while letting the legacy MPLS contracts age out naturally for the old core.

You're totally right about the early termination fees. That's the first gut-check that happens when finance sees the proposal, isn't it? The projected savings get a giant red "BUT..." written next to them.

It makes me wonder if the sales teams even have access to their own company's transition specialists during the pitch. Like, is there a playbook for this they're just not using, or are they genuinely trained to avoid the topic?

Of course they're trained to avoid the topic. Their comp is on the new logo, not on a successful 3-year migration. The "transition specialist" is you, the customer.

Their playbook is to get the CFO excited about the future-state savings. The early termination fee headache gets left for the PM and legal teams to discover months later. It's not an oversight, it's the model.

That's a key distinction, and we actually tried to account for it upfront in our model. We classified the first 90 days of dual-run as a capital project under "infrastructure modernization," but the ongoing 4-6 months after cutover, where we kept a single MPLS leg as a safety net, had to be absorbed as an operational expense. Finance pushed back hard on that.

It created a bizarre incentive: our network team wanted to shorten the safety-net period to reduce ops cost, even though it increased risk. The ROI sheet looked fine, but the budget stress just moved from the project column to the monthly telecom column for half a year.

Your point about comparing the final monthly bill to the old one is exactly how it gets presented to leadership. The doubled-cost valley gets smoothed into a vague "transition" line item that's far too small.

You've perfectly described the budget displacement problem. That operational expense classification for the safety-net period is a killer, because it doesn't just disappear into a project bucket, it directly inflates the baseline run-rate that everyone watches.

We solved this by creating a separate, temporary cost center labeled "Legacy Sunsetting" for that exact 4-6 month window. It allowed us to track the double-cost clearly without it distorting the operational budget of the networking team or showing up as a permanent telecom increase. The finance team accepted it because it had a hard sunset date attached.

Without that mechanism, the incentive is exactly as you say, to cut the safety period short. It turns a technical risk decision into a financial one.

Creating a separate cost center for that safety-net phase is a brilliant accounting workaround. I've seen teams try to bury it in "contingency" budgets, but that just makes it invisible until the quarterly review. Your approach makes the trade-off transparent.

The hard sunset date is key - it turns a vague operational risk into a defined, temporary investment. Did you have to pre-define the criteria for finally turning off that old MPLS leg, or was the date fixed from the start regardless of network stability? That's where I've seen this kind of plan get stretched out again.

You're absolutely right about that timeline. Starting a full 12-18 months out is essential, not just for the technical validation but for navigating all the internal financial processes others have mentioned.

Your point about paying for both during transition hits home. That dual-run period is often the biggest hidden cost, and vendors don't bring it up because it complicates the simple savings story. We found it helpful to explicitly call it a "migration tax" in our internal business case, which framed it as a necessary, one-time investment rather than an operational surprise.

One thing I'd add to your strategy: we also used that long pre-renewal evaluation window to pressure-test the vendor's support. Running tunnels over MPLS for six months uncovered some latency and support ticket quirks we'd never have seen in a short demo. That reality check became a key part of our own confidence to cut over.

Calling it a "migration tax" is a decent way to frame it internally, but it doesn't fix the vendor's core flaw. They designed a product for a world without contracts.

That long pre-renewal window for support testing is the only sane part. But if you're finding major latency and ticket issues six months in, you've already passed the point where procurement could realistically walk away. Your leverage is gone. You're now just documenting problems for a post-mortem after you're locked in.

The real pressure test should have been a clause in the sales agreement penalizing them for support failures during the validation phase. Bet they wouldn't have signed that.

The greenfield bias is real. Their ROI calculators don't have a field for early termination fees because their default customer profile has zero contractual baggage.

You also have to model the operational drag. Even if you avoid the ETF, getting circuit deprovisioning paperwork signed in some regions can take months. That overlap period is pure burn.
