Before updating the software

Download the update

Download the update from the official download location. Do not use updates that you received from an unknown source. Download the update in advance if you are updating a system without internet connection.

Verify the update file integrity and authenticity

Verifying the update file integrity helps identify unexpected changes in the file caused by download issues or by tampering with the file.

NOTE: Do not use an update file for which the integrity cannot be confirmed. In that case, download the update again and check its integrity. Repeat this process until you have a correctly downloaded update file with confirmed integrity.

For details on how to verify the update file integrity, see Verifying file integrity and authenticity.

Confirm system compatibility

Confirm that the update is intended for your PME system before installing the update. It must be designed for or compatible with your software version and your system must meet any other compatibility requirements that are listed for the update.

NOTE: You cannot uninstall a Cumulative Update after it has been installed.

Review release notes

Review the release notes for the update. The release notes provide high level information on the software changes included in the update.
