06Legacy system integration

Connect the system you have—not the system a diagram wishes you had.

When a modern API is unavailable, we use controlled exports, SFTP, vendor utilities, database views, and local agents to move information reliably without forcing a replacement project.

AWhere it shows up

Usually, the warning signs look like this.

01

A critical system only provides scheduled reports or flat-file exports.

02

An on-premises database must exchange data with a cloud CRM or accounting platform.

03

Teams manually download, rename, reformat, and upload the same files every day.

BThe operating path

Built around the real handoffs.

This is the common shape—not a prepackaged connector. During feasibility, we confirm the actual access, rules, volumes, exceptions, and definition of done.

01

Extract

Run a supported report, CLI, database query, file export, or local agent on an agreed schedule.

02

Validate

Confirm delivery, format, period, control totals, duplicates, and required fields before processing.

03

Transform + deliver

Map the legacy structure into the target API, database, or managed file format.

04

Recover

Archive each input, preserve failed records, and support controlled retries without duplicating completed work.

C1Connection methods

Use the access that exists.

  • CSV, Excel, and fixed-width exports
  • SFTP and managed file exchange
  • Command-line utilities
  • Read-only database views and local agents
C2Typical deliverables

Leave with an operating system.

  • Extraction and file contract
  • Transformation and validation service
  • Secure delivery mechanism
  • Archive, retry, and operational runbook
DHosting & ownership

Your infrastructure or ours.

Most automations need a secure backend to run APIs, scheduled jobs, queues, data stores, retries, and monitoring. We deploy that structure where it makes the most operational sense.

01

Your environment

We deploy into your Azure, AWS, Google Cloud, on-premises, or existing server environment and hand over clear operating documentation.

02

Managed by CohesaOps

We host and maintain the backend structure, including monitoring, updates, backups, credentials, and operational support.

03

Co-managed

We operate alongside your internal IT team with the responsibilities, escalation path, and access boundaries defined in writing.

ECommon questions

The questions people ask first.

Short answers to what usually comes up before a scoping conversation. If yours is not here, ask us directly — the intro call is free.

Our system has no API. Is it still possible?
Frequently, yes. Scheduled exports, secure file transfer, vendor command-line utilities, and database views can all support reliable automation when the controls are designed correctly. A missing API changes the approach and the cost, not necessarily the answer.
How do you work with fixed-width or legacy file formats?
They are parsed against a documented layout with validation on every field, duplicate protection on delivery, and archival of the original file exactly as received. Malformed records become exceptions rather than silently corrupted data.
What if the vendor will not help us?
Then we work with what the system already produces for you — the reports, exports, and files you can generate today. It is worth asking in writing first, because a written no is itself a useful scoping answer.
Is it safe to automate against an old system?
It can be, with least-privilege access, a safe test path agreed in advance, and a rollback plan. Where no sandbox exists, we define what a safe production test looks like and who approves it before anything is written.
Should we automate this or replace the system?
An honest question worth asking before spending anything. If a replacement is contracted with a real date close at hand, automating around it may not pay back. If the replacement is a someday, the manual cost is real today.
