Solr Index data reusage for Upgrade, Update and Rehost in Windchill PDMLink
Modified: 19-Nov-2025
Applies To
- Windchill PDMLink 11.1 to 13.0
Description
- For any Solr upgrade/update
- It is time consuming task to re-index the data every time
- For upgrade/update and if the following configurations are not changed, then re-indexing can be skipped, and old indexed data can be reused
Any changes in the collection’s schema require data reindexing. These changes can be:
- Adding/Deleting a Field
- Changing Field’s Type or its Configuration
- Changing Field Analysis
Solr config changes
Changes in update request processor and processor chain might require re-indexing. If processors are modified which might change the Solr document before indexing, then re-indexing is required to reflect the changes
Indexing process changes
Any changes in the indexing process might require re-indexing if the changes are affecting the data which goes in the Solr document for indexing
Eg: In Windchill for an enumerated entry if in previous version only internal name of the entry was getting indexed in a field and now after upgrade, display values of the entries should also get indexed in the same field, then re-indexing is required to index display values as well for the entries
Solr upgrade
When upgrading between major versions, it is always recommended to re-index the data. Refer Solr guide for more information. In case of minor version upgrade if there are no changes in the above mentioned configurations i.e Schema/config changes or Indexing process changes, then re-indexing can be skipped.
For example: Upgrading from 7.x to 8.x will require re-indexing, but while updating from 8.x1 to 8.x2 re-indexing can be skipped if the above mentioned configurations are not changed
