The current version of Sakai at the time Sakai 2223.0 was released was Sakai 2122.23, therefore make sure you upgrade to 2122.2 3 before upgrading to 2223.0. If your on a later version of Sakai 21 22 then you may need to adjust your script to remove lines that you already have run in 2122.3 4 from the 22 script.

2.0 Post upgrade tasks

Elasticsearch

Elasticsearch was upgraded from 1.7.x to 7.16.x and there is no migration path to upgrade the indexes. It will replaced with it’s open source fork OpenSearch. According to OpenSearch the index from Elasticsearch 7 are compatible and it may not be necessary to rebuild the index completely. Here However if your coming from another version of Sakai or have some issue then here are the steps:

1. While the node(s) have been shutdown remove the elasticsearch work directory

2. elasticsearch OpenSearch will begin indexing new documents automatically

3. to add existing previous to the upgrade to the index there are 2 options

   1. rebuild only specific sites

      1. An admin will access each site they wish to rebuild and go to the search tool where they will see the Admin tab

      2. There will be a button to rebuild only this sites index

   2. rebuild all sites

      1. An admin will goto a site with the search tool where they will see the Admin tab

      2. There will be button to rebuild the whole index

      3. Rebuilding the whole index can be a time consuming task and for those with terabytes of data it can take days, therefore it will be wise to perform this task during a low usage time.

      4. Reminder rebuilding the whole index doesn’t have to be done immediately after an upgrade and can scheduled independently, you could even have solution where option a is used until there is a window to rebuild the whole index.
