Update MATLAB Release on MATLAB Online Server

MathWorks^® might release MATLAB^® updates following the general release. An update is an incremental update to the current release. An upgrade is a change from one major release to the next.

Use this procedure to apply MATLAB release updates to a MATLAB Online Server™ instance.

On your license server, update the license manager software to the latest version by following the instructions in Update Network License Manager Software.
On a Linux^® machine, download and then install the latest MATLAB update for the release of your MATLAB Online Server installation.
Create a backup of the working MATLAB image. If the MATLAB update is not successful, you need the backup image to restore MATLAB in MATLAB Online Server.
To create a backup, you can either push the MATLAB image to another repository or push it to the same repository but with a different tag. The commands shown here assume you are using Docker^® as your container management tool. If you are using Podman instead, replace docker with podman in the commands.
- You can use the following commands to save a backup of the existing MATLAB image:
```
docker tag <image-name>:<tag-name> <image-name>:<updated-tag-name>
```
  For example:
```
docker tag containers.mathworks.com/matlab-online-server/mos-matlab-image:1.13.0
containers.mathworks.com/matlab-online-server/mos-matlab-image:1.13.0-backup
```
- For a remote registry, run the following command also:
```
docker push <image-name>:<updated-tag-name>
```
  For a remote registry, the two commands together might look similar to this example:
```
docker tag remote-registry.com/matlab-online-server/mos-matlab-image:1.13.0 
remote-registry.com /matlab-online-server/mos-matlab-image:1.13.0-backup

docker push remote-registry.com /matlab-online-server/mos-matlab-image:1.13.0-backup
```
Use mosadm to build a new MATLAB Docker image. Run this command, replacing <matlabroot> with your actual MATLAB root installation location:
```
mosadm build-matlab-image <matlabroot>
```
For example:
```
mosadm build-matlab-image /MATLAB
```
This command overrides the existing MATLAB image.
Use mosadm to redeploy the MATLAB Pool pod using the following commands:
```
mosadm undeploy matlab-pool
```
```
mosadm deploy matlab-pool
```
