Welcome to the Community, @Kathy4234. I'm here to help ensure you'll be able to successfully migrate Cougar Mountain to QuickBooks Online (QBO).
In addition to what Fiat lux suggested above, I also recommend reaching out to the Cougar Mountain support team for detailed instructions on the migration process. This way, we can ensure that all data will be successfully transferred to QBO.
Once the migration is completed, you'll now have to compare the data of your reports between the two programs. This is to determine which information is transferred and which is not. For guidance, feel free to check these articles:
After checking, you can now start setting up your online company file. To help you with the process, please see this awesome resource: Resources for getting started with QuickBooks Online.
Please let me know how the steps go. I'd appreciate any updates about the migration. If you have any other questions about this, don't hesitate to leave a comment below. I'm just around the corner to lend you a hand. Have a great week ahead.
