Older Versions of MYOB Software Will Be Read-Only Mode from 30 June 2026
Impacted version older than 10 years, including:
- MYOB Accounting Version 24.2 and below
- MYOB Premier Version 19.2 and below
On this date, Activation & Confirmation Server (A&CS) for these products will be decommissioned. After this:
You will no longer be able to make changes to your company file using these versions
Your company file will become read-only after the next confirmation cycle. You can view historical data, but cannot create or edit new transactions unless you upgrade to a supported product
Read-only access allows you to reference past information. This means the software can no longer support for ongoing business operations.
Before Activation & Confirmation Server (A&CS) are decommissioned, you should upgrade to the latest supported version to continue working in your company file.
Why are these versions no longer supported
Older Technical Framework
These versions were built on older technology that no longer works reliably with modern operating systems, the latest compliance framework and environments.
End of Product Lifecycle
As part of the natural software lifecycle, these legacy versions have reached a point at which further updates and improvements are no longer feasible.
Higher Security Standards
New operating systems and security requirements mean older versions can no longer meet today’s security protocols and expectations.
New Compliance Requirements
Modern compliance needs, such as real-time validation and digital reporting features, require newer software capabilities that legacy versions cannot support.
