It is my understanding that BW only lets you keep 60 months data maximum

There is no such conversion software that I know of.  Yes 60 months in the Subledgers and 9 years in the GL. Your reseller should be able to help with current data imports and I would keep the quickbooks desktop available for history. 

Method 1: Talk to your IT guy/gal, about creating a virtual PC for the old Quickbooks PC that can be accessed on your network..                 

Method 2:  I 've been using BW since the mid 90s and at the end of a fiscal year, just before "closing the books" for the year  , I make an EOY backup data file for each company. There is a special USER/PASSWORD created to access these files to prevent users for altering the data or "working" all day in the wrong data set.

Example    ACME2022 ( would include all of 2022,2021, 2020 )   - we keep 3 years of data and 5 years GL

                   ACME2021 ( would have 2021,2020, 2019)

                   ACME2020 ( would have 2020,2019,2018) etc

Prior to the pandemic, I kept 8 EOY files per company "active" , but now i'm only doing 5, the users can access but I have data files named all the way back to ACME2010

In our case we, we typically only get requests for about 5 years old "what did I order on my last order" or warranty

Why 3 years of data verse all 5 years that BW can ?  

 1.We have hit some of the limits in Vendors Invoices (max 12,000)

2. Data access speed and just "junk" clean up. Customers come and go,

I hope your server has been specified to be robust and fast. RAID 5 or 6 with SSDs & Multicore Processor.

Welcome to Sage!  Unfortunately, there is no tool to convert Quick Books into Sage BusinessWorks.   I agree with both DeeDee Heyne and Vince Settipane’s responses to your questions. If you are looking for assistance with this, I would suggest working with your local reseller or Business Partner.  If you do not have one, you can reach out to your sales team by calling 800-447-5700 to request one.  You can keep 60 months for the subledger modules, 9 years for General Ledger.  Using Vince Settipane’s suggestion on creating a copy or archive company at the end of the year is a great suggestion for storing historical data.  In BusinessWorks, you can have up to 999 companies, so you can make copy/archive companies every year and toggle to them when necessary.  Also, Vince Settipane had a good point of storing data and how you can reach the maximum limit for certain transactions.  Please see enclosed articles regarding creating a copy company and maximums for the product.

How do I create an archive company or copy of an existing company?

What are the maximum limits or product specifications
