Legacy and Discontinued Accounting System Migration

Legacy and Discontinued Accounting System Migration

If your data lives in it, we can move it. DOS era packages, discontinued software, custom SQL databases and systems nobody supports anymore are normal work for us. Our team has more than 25 years of data integration experience, and we will get your history into the cloud.

What We Move Over

Real_Time_Access

DOS Era and Old Desktop Software

Accounting packages that stopped being sold or supported years ago.

Automatic_Updates

Custom Databases

SQL Server, Access, FileMaker and other home grown systems.

Enhanced_Collaboration

Unsupported File Formats

Old exports, flat files and proprietary formats.

Integrations

Lists and History

Customers, vendors, items and the history you need.

Data security

Open Balances

Receivables, payables and bank balances that match at cutover.

Simplified_Transactions

Archive Copy

A readable archive of old data that does not need to move.

Financial_Insights

What Needs Care

Very old systems can store data in unusual ways. We test extracts early and agree what moves into the new system and what goes into an archive.

Cost_Effective

Clean Handoff

Notes and training so your team can carry on without gaps.

Why Businesses Are Leaving Older Systems

Common reasons we hear:

  • The software is no longer supported or sold
  • It only runs on one old computer
  • The person who knew the system has left
  • The business needs bank feeds, payroll and modern apps

How It Works

Data_Integrity_and_Completeness

1. Discovery Call

We look at your older systems data, how much history you have and what you want from QuickBooks Online or Zoho Books.

Customization_and_Configuration

2. Fixed Quote

You get a written scope, timeline and price.

Backup_and_Security

3. Extract and Clean

We get the data out, even from old or unsupported formats, and clean it before it moves.

Training_and_Support

4. Migration

We map the data into QuickBooks Online or Zoho Books and connect banks and payroll.

Integration_with_Third_party_Applications

5. Tie Out and Handoff

We confirm the numbers match, then hand everything to you or your bookkeeper.

How long does it take? Most projects take 4 to 10 weeks, depending on how many years of history you bring over and the condition of the data. We agree a cutover date up front so there is no gap in your books.

Questions People Ask

Our system is really old. Can you still get the data out?

Almost always. Getting data out of old and unusual systems is what our team has done for more than 25 years.

We keep a readable archive so nothing is lost, even if it does not belong in the new system.

It helps, but we can often work from the data files or exports alone.

Yes. We work white label for many bookkeeping firms and hand the finished file straight back to you.
