Upgrading the Senzing Entity Resolution Configuration to v4

When upgrading from Senzing v3 to Senzing v4, there are changes to the Senzing Entity Resolution [ER] configuration. The configuration in the database used by Senzing must be updated accordingly.

Generate config upgrade script with sz_dbupgrade

The sz_configupgrade utility, available in <project_path>/bin, is used to compute full Senzing engine configuration update scripts.

Example syntax:

sz_configupgrade -c <INI file> -o <outputDirectory>

Example syntax with example parameters:

sz_configupgrade -c ~/senzing/etc/sz_engine_config.ini -o ~/outputDir

This command generates the sz_configtool upgrade script file from the registered datastore config version version to the current Senzing v4 engine version.

sz_configupgrade -c ~/senzing/etc/sz_engine_config.ini -o ~/outputDir/sz-configuration-upgrade.gtc

Precautions

sz_configupgrade is capable of performing the Senzing engine configuration updates itself with the -a argument and omitting the -o argument. However, this action is not recommended in production. We advise creating and reviewing the scripts with your team to gauge the specific operational impact any changes might have.
