5 min read

Choosing a NetSapiens migration partner shapes how quickly you modernize, what the project costs, and how your customers experience the move.

NetSapiens now supports more than 8 million users worldwide, and Crexendo reports the platform is growing at twice the rate of its competitors.

Before you commit, ask these 12 questions.

Key Takeaways

Automation-led and manual migration produce different outcomes at scale. Know which one you are buying.
Ask for specifics on data transformation, migration validation, sandbox testing, and cutover.
NetSapiens-specific experience matters. General UCaaS experience does not cover the platform's architecture, domain structure, and provisioning model.
Cutover is where customer disruption risk is most visible, so how a partner manages it deserves close attention.
These questions apply whether you are migrating from Metaswitch, BroadWorks, or another legacy platform.

Questions About Automation and Methodology

This is where the specifics matter most: what is automated, what is manual, and why.

1. Is your migration process automated, manual, or a hybrid?

Ask them to describe exactly what is automated and what requires human intervention. Manual-only approaches carry real limitations as subscriber volume and complexity increase.

2. How do you handle data extraction and transformation from legacy platforms?

Configuration structures differ significantly between Metaswitch, BroadWorks, and NetSapiens, so data has to be transformed before it can be provisioned. Ask:

How they extract data from your source platform
How they map it into NetSapiens resellers, domains, users, and configuration profiles
How they validate it before anything goes live

3. How do you validate migrated data before cutover?

Ask for a defined migration validation process, including:

Whether they test migrated configurations in a sandbox environment before anything goes live
How provisioned data is checked against the source, including domain-level validation for customer-specific exceptions
How discrepancies are caught, flagged, and resolved before cutover begins

An experienced partner should be able to walk you through this clearly.

4. Can your approach scale to large or multi-platform environments?

If you manage multiple legacy platforms, multi-tenant environments, or a large subscriber base, your partner's methodology needs to scale with you. Ask whether their process is repeatable across different source platforms and whether it has been applied in environments comparable to yours.

Questions About NetSapiens Experience

NetSapiens has its own architecture, provisioning model, and ecosystem. A partner with general UCaaS experience but limited NetSapiens exposure may spend part of your project getting up to speed.

5. Are you a NetSapiens Ecosystem Partner?

Ask whether the partner has a formal relationship with NetSapiens, what that relationship involves, and how much direct experience they have migrating customers into the platform.

6. Which legacy platforms have you migrated from into NetSapiens?

Metaswitch and BroadWorks are common source platforms, but their data structures and migration complexity differ. Direct experience with your source platform can help a partner anticipate platform-specific issues earlier. Ask for examples.

7. How do you stay current with NetSapiens platform changes?

NetSapiens continues to evolve. Ask how the partner tracks platform updates and how those updates are reflected in their migration methodology.

Questions About Customer Experience and Risk

Your customers will not know or care about the platform change. They will notice if their service is disrupted. Cutover and rollback planning are where that risk is managed.

8. How do you manage cutover to minimize customer disruption?

Cutover is a critical moment in any migration. Good telecom cutover planning should cover:

How subscriber moves are sequenced, whether in stages, batches, or by customer group
How rollback is handled if something goes wrong
What communication is recommended for end customers

Read more about what a smooth telecom cutover requires.

9. What does your rollback process look like?

Ask what a rollback involves, how quickly it can be executed, and who owns the decision to initiate it. A clear answer here is a good sign.

10. How do you handle customer-facing features that do not map directly between platforms?

Feature parity between legacy platforms and NetSapiens is not always one-to-one. Call recording, receptionist consoles, fax services, and contact center integrations are common examples that need careful review. Ask how your partner identifies gaps, communicates them, and resolves them before customers are affected.

Questions About Economics and Outcomes

Every week a legacy platform stays live has a cost. The right partner can explain specifically how their approach affects engineering hours, elapsed timeline, and the pace of legacy retirement.

11. How does your approach affect the total cost and timeline of migration?

Ask them to explain how their methodology affects:

Engineering hours required across the program
Elapsed time from kickoff to full cutover
The cost of maintaining legacy platforms during the migration window

If you are carrying two platforms during migration, elapsed time can directly affect operating cost. Fuse.Cloud, for example, completed a BroadWorks to NetSapiens migration estimated at about 18 months of manual effort in roughly six months (read the case study). Understand the real cost of delayed migration before you commit to a timeline.

12. What does post-migration support look like?

Migration does not end at cutover. Ask:

What happens in the days and weeks after customers are moved
Whether features are validated from the client side, including SNAPmobile and other end-user apps
Who owns support during that period, and how issues are escalated and resolved

Comparing Partners?

The right partner should be able to answer all twelve questions with specifics about your environment, not general assurances.

Frequently Asked Questions

What is a NetSapiens migration partner?

A NetSapiens migration partner is a company that specializes in helping service providers move customers, configurations, and data from a legacy telecom platform into NetSapiens. Strong partners combine platform-specific expertise with a defined methodology for discovery, data transformation, validation, cutover, and post-migration support.

How is automated migration different from manual migration?

In a manual migration, engineers extract, reformat, and provision data by hand, which introduces variability and limits how quickly the work can scale. An automated approach uses software to handle extraction, normalization, and provisioning, reducing manual effort, improving consistency, and shortening timelines. See how automated and manual telecom migration compare.

What platforms can be migrated into NetSapiens?

NetSapiens migrations commonly originate from Metaswitch and BroadWorks, though other legacy voice and UCaaS platforms are also migration sources. Complexity depends on the source platform's data structure, the size of the subscriber base, and the degree of customization in the existing environment.

How long does a NetSapiens migration take?

Timelines vary with the size and complexity of the environment, the source platform, and the methodology used. Automation-led approaches can significantly compress timelines compared to manual processes. A credible timeline should account for the actual environment, including subscriber volume, configuration complexity, and cutover requirements.

What should I do before engaging a migration partner?

It helps to have a clear picture of your current environment: the source platform, approximate subscriber count, any custom configurations or integrations, and your target go-live window. The more clarity you provide upfront, the more accurate the partner's scoping and planning will be.
