  +5. If upgrading Lagoon Core, and you have enabled groups/user syncing for OpenSearch, you may additionally need to run the `sync:opendistro-security` script to update the groups in OpenSearch. This command can also be prefixed with a `GROUP_REGEX=<group-to-sync` to sync a single group at a time, as syncing the entire group structure may take a long time.
  +
  + ```
  + kubectl --namespace lagoon-core exec -it deploy/lagoon-core-api -- \
  + sh -c yarn sync:opendistro-security
  + ```
