MYOB can take the hassle out of upgrading—you can send your file to us and we'll put it online for you and let you know when it's ready to use.
Upgrades usually take a couple of hours (depending on your company file size), and you can't make changes to your file during this time, so you should do it outside of business hours.
Start AccountRight (look for the new AR shortcut icon on your desktop or in the Start menu). The Welcome window appears.
Click Upgrade a company file. The Upgrade Assistant appears.
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.
If the file you're upgrading is password-protected, type in the password and click Continue.
