Upgrade Instructions

These are the upgrade instructions if you upgrade from version 2.2.3. If you are upgrading from an older version (e.g. v2.1.5) please follow the upgrade instructions on Squirro 2.2.0 - Release Notes

This is not the latest version of Squirro. To upgrade to this version, please ensure that you point the squirro yum repository to version '2.2.4' and not to 'latest'.

If you are using Squirro in a Box, then there are additional steps involved. In this case, please contact support.

This upgrade will re-index all existing, mapping version 4 based elasticsearch indices (squirro_v4*) into new, version 5 based indices (squirro_v5*). Therefore you need to make sure that you have at least 50% free diskspace on your storagenodes.
Depending on your collection size, this re-indexing can take a long time, please be patient. After the upgrade both indices (v4 and v5) for all projects will exist, but only the v5 will be used. A future upgrade will remove all v4 base indices (if you haven't done that manually by then).

1. Upgrade Storage Nodes

If your storage node runs in the same Virtual Machine or Operating System as your cluster node, skip this step. Otherwise upgrade all storage nodes one at a time by running:

[squirro@storagenode01 ~] sudo yum update

2. Upgrade Cluster Nodes

[squirro@clusternode01 ~] sudo yum update
