Why software migrations break

The new system is ready. The old one won’t cooperate. Export functions cap at 10,000 rows. APIs throttle bulk reads. Custom fields live in formats the vendor never documented. Most migration tools assume clean access to clean data. When the source system fights back, you need engineers who extract data from hostile environments for a living. That’s what we do.

Uncooperative sources handled

No API? Throttled exports? Proprietary format? We scrape, reverse-engineer, or parse whatever the source system gives us.

Every record validated

Automated checks on every object type. Dry run with a full validation report before we touch production.

Zero team downtime

Migration runs parallel to your live system. Your team switches over in a single planned window.

Any platform, any direction

SaaS, on-premise, legacy databases, spreadsheets, or systems with no export at all.

What most teams try first

Built-in export and reimport

The appeal

Most software has an export button. Download a CSV, clean it up, upload to the new system.

Where it breaks

Standard fields transfer. Activity history, relationships between records, and custom objects get dropped. Row limits and throttled APIs mean you never get everything in one pass.

Vendor migration tool

The appeal

Your new vendor offers an import wizard for common source platforms.

Where it breaks

Covers the happy path: standard objects, standard fields. Custom configurations, historical data, and anything the source vendor doesn’t expose through supported channels gets silently skipped.

Internal IT team writes scripts

The appeal

Your team knows the data model. They can write extraction and loading scripts.

Where it breaks

Works until the source system throttles API calls, rate-limits exports, or stores data in undocumented formats. Migration is a one-time project that demands scraping and reverse-engineering skills your team doesn’t use daily.

Why off-the-shelf migration tools fail here

Generic migration tools assume both systems play nice. They need clean API access on both ends. When the source system restricts exports, hides fields, or uses proprietary data formats, those tools stop working. A custom pipeline adapts to whatever the source system actually gives you, not what it’s supposed to give you.

Built for these situations

Organizations leaving a vendor that makes it hard to export your own data
Teams whose source system has no API, a throttled API, or an API that doesn’t expose everything
Companies consolidating multiple legacy systems into one platform
Anyone who tried the built-in export and discovered half their data didn’t come through
Regulated industries where data must stay on your infrastructure during the migration

From locked-in to live on the new system

01

Source assessment

We audit your source system’s data model, export capabilities, and access constraints. You get a written report covering what exports cleanly, what doesn’t, and how we’ll extract the rest.

02

Extraction build

We build the extraction pipeline. API calls where possible, scraping or reverse-engineering where not. Every record captured, including the data the export button leaves behind.

03

Transformation logic

Scripts to clean, normalize, and restructure your data for the target schema. Field types converted, relationships preserved, duplicates flagged.

04

Test migration

Full dry run into a sandbox. Automated validation report covering record counts, field integrity, and relationship checks. You review and sign off.

05

Production cutover

Live migration with rollback capability. If validation flags any discrepancy, we revert in minutes. Your team switches over in one planned window.

06

Post-migration check

Automated integrity verification on every migrated record. 30 days of support for anything that surfaces after go-live.

Why teams choose Stratalis for software migration

Scraping is our core skill

We’ve spent 15 years extracting data from systems that don’t want to give it up. Vendor lock-in, anti-scraping measures, undocumented formats. This is what we do every day.

Flat-rate pricing

You know the full cost before we start. No hourly billing, no surprise overruns when the source system turns out to be harder than expected.

Engineers, not account managers

You talk directly to the people writing the extraction and migration scripts. No layers between your question and the answer.

Rollback on every cutover

No data is overwritten until validation passes. If anything looks off, we revert to your pre-migration state in minutes.

FAQ

We extract data through whatever channel works: screen scraping, database access, file parsing, or reverse-engineering export formats. No API is not a blocker for us.

Yes. If the data is visible in the application, we can extract it. We’ve built pipelines from systems with no export function at all.

Included in the flat-rate quote. Duplicates, inconsistent formatting, orphaned records. Cleanup happens as part of the transformation step, not as a separate project.
