4. Manual Maintenance Upgrade

Use this procedure to perform a manual upgrade from one HDP maintenance release to another. If your cluster is running HDP 2.2 or HDP 2.3, you can perform a manual upgrade to a later maintenance release of that HDP version. For example: you can upgrade from HDP 2.2.x to HDP 2.2.y OR from HDP 2.3.x to HDP 2.3.y. You are strongly encouraged to read completely through this entire document before starting the upgrade process, so that you understand the interdependencies and order of the steps. It is highly recommended you validate these steps in a test environment to adjust and account for any special configurations for your cluster.

The high-level process for performing a Manual HDP Maintenance upgrade is as follows:

	Note
	This process is an alternative to the Rolling Maintenance Upgrade feature. If you meet the Rolling Maintenance Upgrade Prerequisites, you can consider that process.

	Important
	If you need to upgrade between minor HDP stack releases (such as HDP 2.2 to HDP 2.3), refer the the sections about Minor Upgrades, Rolling or Manual.
