When I installed High Sierra, it put my QB 2009 in an “incompatible” folder, so I cannot access it. Will the 2019 version find what it needs anyway? It is backed up (.qbmb), but the last I created this file type was in December. Will it convert from the application or from the backup?
Allow me to provide clarifications about file conversion in QuickBooks Desktop for Mac.
Yes, the 2019 version of QuickBooks for Mac will be compatible with your newly installed operating system High Sierra. That said, it is accessible. On the other hand, you'll need to convert your data from the backup copy that you've created. This will only happen if you've already upgraded to the latest version of QuickBooks.
The process goes like this:
Upgrade your QuickBooks to the latest version.
Restore the backup copy that you have from the 2009 version to the new one.
Once done, you'll need to update the data so it will be updated to the 2019 version and start using it.
For the steps in performing this process, please refer to the articles that I've provided above.
Please let me know how it goes or if you have any follow up questions with this concern. I want to make sure you're taken care of. Wishing you all the best.
