Upgrading MapR Core Without the MapR Installer

You can upgrade MapR core without using the MapR Installer.

First, you perform an offline or rolling upgrade of the MapR core manually. Next, you configure the new version to enable support of MapR core features. Finally, you upgrade ecosystem components manually.

When upgrading, you can install packages from one of the following sources:

MapR Internet repository
A local repository
Individual package files

See the next topic to begin setting up repositories.

When you are finished upgrading MapR core, follow the steps to upgrade the ecosystem components, as described in Upgrading the Ezmeral Ecosystem Pack Without the MapR Installer.

NOTE MapR 6.0 and later releases are only compatible with EEP 4.0.0 and later EEPs (see EEP Support and Lifecycle Status). If you upgrade core to release 6.0 or later, you must install or upgrade to EEP 4.0.0 or later. Clusters with EEP 3.0.1 or later are allowed to upgrade to MapR 6.0 or later, but such clusters must not enable new features, add new services, add new nodes, or make configuration changes until EEP 3.0.1 or later is upgraded to EEP 4.0.0 or later.

Then proceed to Finishing the MapR Core Upgrade.
