[GNC] How to Upgrade from GNU 4.11 to latest version (5.21)

[CJN.... ...]

22 September 2025

Hi Help Support Team

I have been using GNU 4.11 since early 2022.

But I notice a newer Version than the 4.11 installed on my laptop in 2022.
Can you advise exactly how I could Upgrade by installing update to 5.21 version to my current laptop, without losing any data?

As I am also planning to upgrade my Laptop in next couple of months, any advice on the process of installing and transferring GNU package & data to a new machine also welcomed

And as I am definitely not a geek type computer expert, nor accountant, I've slowly found my way round the accounting package to keep my records in order.
Great for managing my very simple income & expenses data.
Now trying to find my way into the Help network - hope I'm submitting this in correct process 🙂.

Thanks in advance

Chris
