# Upgrade P4 Search

You can upgrade P4 Search to a newer release. This gives you support for new features in other Perforce products and security fixes.

P4 Search 2024.2 or earlier: When you upgrade, P4 Search automatically migrates your index to the new index structure. The time taken for the migration depends on the size of your index. It can be as short as a few minutes for a small index and several hours for a large index. You can check the migration by going to the Elasticsearch Hosts service status on the P4 Search Service Status page. See Check the status of P4 Search.

During the upgrade, if you add a self-signed certificate into the Java Runtime Environment (JRE), the following JRE directory gets overwritten:

/opt/perforce/helix-p4search/jre

## Before you begin

- Upgrade the P4 Plugin Filter to the same version as P4 Search and then restart Elasticsearch. See Upgrade Elasticsearch.

- Check the requirements for P4 Render and P4 DAM:

  - If you upgrade P4 Search, you must upgrade P4 Render to the same version..

  - If you upgrade to P4 Search 2024.3, you must also upgrade to P4 DAM 2024.5 or later. See Upgrades in the P4 DAM Documentation. If you upgrade to P4 Search 2024.2 or earlier, only P4 DAM 2024.4 or earlier is supported.
