How long does a Sage 100 to Acumatica migration take?

For many small and mid-sized businesses, a Sage 100 to Acumatica migration takes about 3 to 6 months from initial assessment through go-live. The timeline depends on the number of entities, modules, integrations, reports, and how much historical data needs to be included. Simpler projects may move faster, while more complex environments can take longer. Milestone scopes each migration individually and provides a more specific timeline after the initial assessment.

How much internal time will our team need to commit?

Your team's heaviest involvement usually comes during discovery, scoping, data cleanup, testing, and go-live preparation. Finance and operations leads should expect to review data, answer configuration questions, and sign off on key decisions throughout the project. As a rough guide, your internal project lead should plan for 3 to 5 hours per week during the migration. Data cleanup can take more time depending on the condition of your Sage 100 data, and end users usually get involved closer to go-live for hands-on training.

Can our Sage 100 reports and custom fields be rebuilt in Acumatica?

In many cases, yes. Milestone reviews the reports, custom fields, UDFs, and reporting logic your team relies on today during discovery and design. Some items may be rebuilt in Acumatica exactly or very closely, while others may be improved based on how your team wants to access information in the new system. For some teams, the goal is to keep familiar reports in place. For others, it is to take advantage of Acumatica's newer reporting and visibility. Milestone helps you decide what should be replicated and where it makes sense to improve how information is delivered.

Can Milestone Information Solutions help us evaluate whether moving from Sage 100 to Acumatica makes sense?

Yes. Milestone helps businesses review their current Sage 100 setup, reporting needs, workflows, integrations, data, and long-term goals before deciding what the next step should be. The first step is usually a discovery conversation, where we talk through what is working today, what needs to change, and whether Acumatica is the right fit for the business.

Sage 100 migration process

A successful Sage 100 migration follows a clear process, even when every project is unique. Milestone follows a structured path from assessment through go-live and ongoing support, so your team knows what to expect at each step.

1. Assessment and Migration Roadmap

We review Sage 100 modules, add-ons, integrations, multi-entity structures, and the workflows your team depends on before any data is moved.

2. Design and Mapping

We map accounts, classifications, custom fields, reporting dimensions, and process changes into Acumatica so the new system is aligned with how your business needs to operate.

3. Data Migration

Once the data is cleaned, we extract and load it into Acumatica, then have your team test and validate it before go-live.

4. Training and More Testing

We train employees on the new system, document procedures, and validate balances, aging, and key reports before go-live.

5. Go-Live and Ongoing Support

Your team goes live with Milestone support in place. We stay closely involved during the first few weeks after go-live to answer questions, resolve issues, and help users settle into Acumatica. From there, we continue providing ongoing support as your system, team, and business needs change.
