Changing the product edition manually, one node at a time

You can manually change the IBM Storage Scale product edition from your currently installed product edition, one node at a time.

Use the following steps to change the IBM Storage Scale product edition manually, one node at a time.

Important: If the cluster where you plan to make a supported edition change has an interim fix (efix) applied to its IBM Storage Scale version, you must either upgrade to a version with no interim fix applied, or contact IBM Storage Scale support team.

Tip: In the following steps, rpm and dpkg commands are used for installing and uninstalling packages. If the respective repository is set up in your environment, you can also use package manager commands such as yum, zypper, and apt-get for installing and uninstalling packages.

Remember: According to the edition that you are changing to, replace License_Package_Name and gpfs.license.x in the following procedure. Use the next table as reference.

Edition	License package name
IBM Storage Scale Data Access Edition	`gpfs.license.da*`
IBM Storage Scale Data Management Edition	`gpfs.license.dm*`
IBM Storage Scale Advanced Edition	`gpfs.license.adv*`

Download from IBM® Support Fix Central the installation image of the IBM Storage Scale edition that you are planning to change to.
