You are upgrading your Symantec Endpoint Protection Manager (SEPM) to version 14.2 MP1, and the SEPM upgrade fails with an error.
The SEPM upgrade fails with SQL error "SQLState: S0001 Argument data type bigint is invalid for argument 1 of substring function."
A data type for the column SOURCE_COMPUTER_IP is set incorrectly in the ALERTS database table. An index dependent on this column is preventing the upgrade script from changing it.
You will need to delete the index that references SOURCE_COMPUTER_IP prior to continuing with the upgrade. Be sure to test your changes and back up or snapshot your production database before proceeding. If you wish, you can re-create the index after you are finished.
