While running migration the database update fails with Errors for PACKAGE ENDPOINTUTILITY
Known issue when migrating from versions prior to 15.7 to 15.7 and Oracle 19c
Download the 15_7_Schema_Objects_Validation_b.zip from the portal in the 15.7 files and extract it to the C:\Program Files\Symantec\DataLossPrevention\EnforceServer\15.7\Protect\Migrator\SQL folder
See page 30 of the 15.7 upgrade guide for details.
After the old .sql file has been updated with the new .sql file rerun the migration utility.
