Upgrade to the new AccountRight

AccountRight Classic (v19 and earlier) is being decommissioned on 28 February 2026. MYOB will be turning off activation and confirmation for AccountRight Classic on this date. After this, if you're still using AccountRight Classic, you'll no longer be able to make changes to your company file.

To keep working, you need to upgrade. Learn more about your upgrade options

If you're upgrading from a classic AccountRight version, like v19 or earlier, here's how to install the new AccountRight and upgrade your company file to work with it.

Not sure what version of AccountRight you're on? To check your current version, go to the Help menu and choose About AccountRight.

If you're already using the new AccountRight and want to update it, see Getting the latest version.

About upgrading

Upgrading is a straightforward task. You start by downloading the new version, finding your company file and sending it to us to upgrade and put online.

Before you begin

1. Download and install AccountRight

Use Google Chrome to download the file ( download Chrome here ). We've seen cases where other browsers, like Internet Explorer, can affect the file extension of downloaded files.  What browser am I currently using?

  1. Right-click here and choose Save file as or Save target as and save the file to your Desktop.

  2. Double-click the installer file you've saved to your computer to install the new AccountRight version.

2. Upgrade your company file

MYOB takes the hassle out of upgrading. When you upgrade, we'll upgrade it for you, put it online and let you know when it's ready to go.

Note that upgrading can take a couple of hours (depending on your company file size), and you can't make changes to your file during this time, so we suggest you do this outside of business hours. 

Don't want to put your file online? In the following cases, you may want to upgrade your file and store it offline:

  • don't have an internet connection, or it's very slow

  • or don't have a subscription for an online file

  • or want to work on a local network.

Note that you won't have access to key features.

  1. Start AccountRight (look for the new AR shortcut icon on your desktop or in the Start menu). The Welcome window appears.

  2. Click Upgrade a company file. The Upgrade Assistant appears.

  3. Click Continue and on the Company file page, click Browse to locate and select the file you want to upgrade.

    Can't find your file? Try looking in your AccountRight v19 installation folder, like c:\Plus19 or c:\PremierClassic. Look for a file with a .myo or .prm extension. If you can only find a .MYOX file, it means it's already upgraded (learn how to open a company file).

    Still having trouble? Get help  finding your company file.

  4. If the file you're upgrading is password-protected, type in the password and click Continue. If you're not sure of the Administrator password, try leaving it blank.

  5. Sign in to AccountRight with your MYOB account details and then click Upload.

  6. Once your file has uploaded, you can close AccountRight while we do the rest. 

  7. We'll email you when the upgrade's complete, or if we come across any issues along the way.

For information on how to open your file in your new software, see Open a company file.

3. Complete post-upgrade tasks

After you get your upgraded file back, there may be a few more things you need to do (depending on the features you want to use), such as migrating your personalised forms. Don’t stress though, you only need to do them once.

Check out this help topic for all the details, or watch this video for an overview:

What should I do with my old AccountRight software? If you need access to pre-upgraded company files or backups, keep your old AccountRight software installed on your computer. This also lets you run historical reports in your old software. Otherwise you can uninstall your old AccountRight software.
