Data Hub Module
Upgrading the Data Hub Module
As part of the upgrade process Spectrum™ Technology Platform backs up these two files from the previous version:
- SpectrumFolder\server\modules\hub\hub.properties
- SpectrumFolder\server\modules\hub\db\neo4j.properties
You can use these backups to restore any changes you made to these files. To restore changes that you made to these files, open the new files and edit the property settings that you want to retain from the previous version. It is imperative that you do not simply copy the old file over the new file to restore the previous settings, as some properties may have been added or removed in the new release.
If you are upgrading Spectrum™ Technology Platform from a version earlier than 12.0, the neo4j.properties file has changed significantly due to the neo4j update from 2.x to 3.x. ReviewSpectrum\server\modules\hub\DataHubUpgrade_From_PreV12_README.txt for full details.
Upgrading Data Hub Indexes
Spectrum™ Technology Platform 2019.1 implements an improved indexing method for better performance. As part of the upgrade to 2019.1, existing indexes will automatically be converted to the new format.
Indexed properties are now restricted to a maximum length of 4036 bytes. If a model has an indexed property that exceeds this limitation, you will not be able to open that model until you complete the following steps.
