There are two separate cases for a MATLAB upgrade:

1) Installing a new general release version of MATLAB.

2) Installing a web update to a MATLAB version (also know as a plus '+' release).

General Release Upgrade

When you install a new version of the general release, you will simply install the new version of MATLAB into a new folder. The installer will not overwrite any other versions that are already installed. If you have a network installation of MATLAB, the network license manager will need to be updated before you can run the new version of MATLAB.

For the complete instructions on how to install MATLAB, please refer to the installation guide here:

Install Products

https://www.mathworks.com/help/install/install-products.html

Once the new version is installed, you can remove the previous installation of MATLAB, or leave it installed if you wish.

NOTE: When uninstalling, if you are prompted to deactivate, do not do so. Deactivation will also remove your license for the new release.

Plus Release Upgrade

If you are upgrading from a standard release to a plus (+) release (e.g. upgrading R2006b to R2006b+), you will need the installation files only for the products that have updates. The plus releases are only available through downloads. Once you have downloaded all of the updated files, launch the installer that was downloaded with the plus release files. For more information about this installation process, see the related solution: "How do I install additional toolboxes into an existing installation of MATLAB?"

@Theja sai

General Release case:

You install the general release into a new folder. No files are removed; any file you modified before will still be where it was.

If you modified some of the Mathworks-supplied code (not advised!!!) then your modifications will not be copied into the new directory.

When you do a general release installation, if MATLAB detects that you have installed packages using the Add-On Installer, then MATLAB will offer to install the packages into the new release as well.

Pluse Release case:

Plus releases do modify files in the current installation directory. If you have modified some of the Mathworks-supplied code (not advised!!!) then your modifications might possibly be overwritten.

In both cases, any source code you might have in your own directories will not be affected.

It is advised that you never modify any of the Mathworks installed code.
