Upgrading

This section describes the process to upgrade CES HDFS Transparency.

Note:

Upgrading to version 3.2.2-stream is only possible from gpfs.hdfs-protocol version 3.2.2-5 or higher. Therefore, users must first upgrade to version 3.2.2-5 before proceeding to upgrade to any version from 3.2.2-6 onwards. For example: If users intend to upgrade from version 3.2.2-1 to 3.2.2-8, they must initially upgrade from 3.2.2-1 to 3.2.2-5, and subsequently proceed from 3.2.2-5 to 3.2.2-8.
To upgrade to version 3.1.1-stream, users must have gpfs.hdfs-protocol version 3.1.1-14 installed. Hence, it is necessary to first upgrade to version 3.1.1-14 before attempting to upgrade to any version from 3.1.1-15 onwards. For example: If users aim to upgrade from version 3.1.1-10 to 3.1.1-17, they should initially upgrade from 3.1.1-10 to 3.1.1-14, and then proceed from 3.1.1-14 to 3.1.1-17.
