Upgrade MATLAB Release

Upgrading involves installing a newer general release than the current installation on your machine; for example, from R2018b to R2019a. The Software Maintenance Service on your license must be current. For additional information, see MathWorks Software Maintenance Service.

To upgrade an existing installation:

  1. Run the MATLAB® installer. If you do not have it on your machine, you can get it from the Downloads page on the MathWorks® website.

  2. Install the upgrade in a new installation folder. This is true whether you are upgrading from a previous version or upgrading from a prerelease version of the same release.

You do not need to delete an existing MATLAB installation before installing a new release. Each release is independent of previous releases and you can run multiple releases on the same system.


The upgrade will install only those products current on your license. For example, if your existing installation includes ten products, but your current license only includes nine of those products, your MATLAB installation upgrade includes only the nine products in your current license.
