Hi Andrew Kreismann

You will need to:

1. Install the 2015 Accountant Edition Trial (but do not open your file in this version).
2. Install the 2022 version
3. Restore your .CAB backup in the 2022 version

Follow the steps in this link to convert your existing data to preserve the exact transactional copy of your data for use in the 2022 version. If you only wanted the Chart of Accounts, Customers, Vendors, Employees records, after you follow the conversion steps, you can build a new file with only the 'skeleton' of your existing company by following this link. You are not able to import any invoices or prior transactions with this 'skeleton' option. Hope this helps.

Just one small adjustment to the response from DeneshS. The indication is that you should install 2015 Accountant Edition. In my experience installation of any Edition of Sage 2015 will work unless this is a recent change.

Alwyn Great point, but I usually recommend to install the Accountant Edition because users historically have mistakely opened the data file in the wrong flavour of 2015 instead of the latest version and converted their data file to a higher flavour and can no longer be downgraded easily.

Good point Denesh, if we can save further problems for the user all the better.
