To update a Platform product, get the corresponding database update scripts from Platform and update the database schema before you update the cluster.
For Symphony 4.1, get upgrade_sym_data_3_2_to_4_1.sql
Extract the database update scripts to any directory.
In the command console, change to the SqlServer/Patch subdirectory. For example, if you extracted the scripts to sym41_temp:
cd sym41_temp/DBschema/SqlServer/Patch
Run the scripts in this directory to update the database schema.
