We recognize the need to use financial exchange with the old QuickBooks Point of Sale version, MNINursery. 

Since QuickBooks POS has already been discontinued, you can still use the old system if you're exporting data from the program. Thus, as mentioned by my colleague, Kevin_C, above, you may use any of the other four methods to exchange data between the stores, and that includes the following:

• Desktop email
• Web-based email
• Removable Media
• Network file transfer

You may refer to the Configure Point of Sale Store Exchange section outlined in this guide for more detailed information: Store Exchange Overview.

Moreover, I've included this handy resource to further guide you with additional details about the product's discontinuity: QuickBooks Desktop Point of Sale discontinuation.

We'll keep our ears open for any added queries when handling QuickBooks POS. Please don't hesitate to let us know in the comments below, and we'll get around to providing further help. Keep safe.
