When you upgrade Advanced Matching, Data Normalization, and Universal Name from Spectrum Technology Platform, you must first back up the contents of the following folders so that you can restore the data, such as indexes, matching tables, and configured properties later if anything goes wrong during the upgrade.
- cdqdb
- matcher
- parser
- search index
- tables
Note: Backup the elasticsearch.template file if you are using the snapshot and restore functionality in search index. The properties file is placed at: SpectrumDirectory/index/elasticsearch.template.
Any changes made in the elasticsearch.template file must be made in the new file called opensearch.template.
