How to update or upgrade and what is the difference

The version number

The program's version is always visible on the title bar of the main window of the program. It consists of 4 numbers separated by dots, e.g. 2.0.0.225. The version number uses the following pattern:

[major].[minor].[maintenance].[build]

which mean the following:

• [major] –  the first position indicates the major version number. It changes only when the entire program structure is changed, or some significant features are introduced to the software.
• [minor] – the second number changes when planned improvements or minor features are implemented (this usually happens every quarter; see version history).
• [maintenance] – the third number changes only when some important bug fixes need to be applied to the program and cannot wait for the next minor version change. 
• [build]– the last number changes automatically every time the Development team compiles a new build during the development cycle. This number is usually meaningless for the end-user.

Upgrade

An upgrade is when you reinstall the program by using a newer version of that program, with a higher first figure of the version number. For example, your currently installed version of the program is 1.6.4.9, and you replace it with version 2.0.0.15.

The upgrades are usually not free but cost less than new licenses. Before you attempt to upgrade a program, visit the Pricing page of the product (e.g. CodeTwo Backup) to find out if you are eligible for a discount or check your purchase options.

Update

An update is when you reinstall the program by using a newer version of that program, with a higher second, third or fourth figure of the version number. For example, your currently installed version of the program is 2.0.0.15, and you replace it with version 2.1.0.10. Updates are free of charge for all product license key owners.

You should update your existing installation on a regular basis to make sure you always use the current version of the program, with all new features included and all known bugs removed.

4. If you have more instances of the program in your environment, perform the update on each machine where the program is installed.
5. After the update process is complete, you can launch the program. All of your settings and jobs are retained.
