## Upgrading to 16.0.100

Category | Description
--- | ---
Java version | ALM Octane 16.0.100 requires JDK 11. You must install JDK 11 before upgrading ALM Octane.
Elasticsearch version | ALM Octane 16.0.100 requires Elasticsearch version 7.16.2. If you are using an earlier version of Elasticsearch, you must upgrade to 7.16.2. Note that you cannot upgrade to ALM Octane 16.0.100 if you still have indexes created in Elasticsearch 5.x which have not yet been re-indexed (as described in previous upgrade guides). To verify that all your spaces are up-to-date, open Settings > Site > Spaces. The ELS Maintenance Status of all your spaces should be Done.
Supported upgrade path | The current release is a long term path release (LTP), meaning that you can upgrade to ALM Octane 16.0.100 either directly from 15.1.20, or from 15.1.90.
LTP upgrade | If you are upgrading from 15.1.20 (previous LTP release), there are various pre-upgrade and post-upgrade steps required, as described in the upgrade guide. Caution: To roll back the LTP upgrade, you will need your pre-upgrade configuration files from each node. Make sure you save a copy of the configuration files in a secure location before upgrading. You cannot roll back without these files. This includes octane.conf, and any other configuration files in /opt/octane/conf. For details on what was added in each of the service packs since the previous LTP release, see: What's new in 15.1.40 What's new in 15.1.60 What's new in 15.1.90
