You need to define exactly which version you are upgrading from and to.

2015 Quantum will upgrade to 2022 or 2023 Quantum.

2015 Premium will upgrade to 2022 or 2023 Premium or Quantum.

2015 Pro will upgrade to 2022 or 2023 Pro, Premium or Quantum.

Upgrading from Sage 50 Canadian 2015 Quantum to Sage 50 Canadian 2022 Quantum is as simple as backing up your original file in your 2015 version, installing the 2022 version and opening the exact same file in the 2022 version.  The conversion will start automatically.

You should be aware that 2022 may not be available in too many places so you may be upgrading to the 2023 version but the process is the same.

I am hoping to move my data from Sage 50 Quantum Accounting (Release 2015.3) to Sage 50 Canadian Pro 2022 (or as you say, Pro 2023). Notice how I do NOT want to continue with Quantum as it is overkill for our purposes, size, and the transactions we record. Pro will be more than adequate and this is where I need help as it is not a straight forward conversion. Backing up the old data and trying to restore in the new version does not work when switching from Quantum to Pro.  

Ok, upgrading year but downgrading version from Quantum to Pro.  You are correct, it is not a straight forward conversion.  Sage has no known method of doing this with the end user interface.  Pro to Premium or Quantum is easily possible but the reverse is not.

The generally accepted method of doing this is to create a brand new file, export lists from your current file and import them into the new file.  However, this does not include transactions in the past.  It can usually be done by a SAN member who has experience with this kind of thing more quickly but can be done by you if you understand the setup of a file.  It takes a bit of time to get the opening balances in correctly in some files with a lot of customers, vendors, employees and inventory.  It is possible I might be able to help you out doing this through a data repair method that will keep all transactions.  This is something I do charge for.  You can contact me by private message or the email address in my Profile, under Contact.  Just click on my name to find it.
