Transitioning from legacy ISYS document content indexing

If you have been using document content indexing (DCI) in Content Manager before version 7.2, your indexes would have been created by the ISYS indexing engine. Since version 7.2, ISYS technology is not in use in Content Manager any longer and document indexing is powered by Elasticsearch.

An Content Manager upgrade to the latest version does not delete the legacy DCI files. However, after the upgrade, Content Manager Enterprise Studio does not recognize the ISYS indexes any more, which makes document content searching in Content Manager unavailable. A mixed ISYS/Elasticsearch or ISYS/IDOL environment is not supported.

It is recommended for upgrading customers to set up Elasticsearch document content indexing and then index the entire dataset to create the indexes. Follow the instructions in Setting up document content indexing and searching to start the process. From Content Manager version 9.0, ISYS content indexing is unsupported.
