+# db_upgrade_remote.sh: This script is to perform database schema upgrade on remote db,
+# no shecma downgrade will be performed in case db_version is higher then target_version
+#
+# Logic: 1. Get target schema version from db scripts in $POLICY_HOME/data/mysql
+# 2. Get current db schema version from support.db_version table (of target system)
+# 3. Apply db upgrade script in order if target_version is HIGHER than db_version
+# 4. Print out warning message if target_version is LOWER than db_version
+# 4. Print out message if target_version is EQUAL to db_version
+#
+#
+# Usage : db_upgrade_remote.sh db_user_id db_user_password hostname
+# Example: db_upgrade_remote.sh policy_user password localhost.com
+#
+# Assumption: 1. DB schema upgrade script in $POLICY_HOME/data/mysql folder with read permission
+# 2. DB user has privilege to create/drop/alter database table
+#
+# Note: The default location for db schema upgrade script is $POLICY_HOME/data/mysql
+# The release level is represented as Two-digit-Year+Two-digit-Month+two-digit-Sub-release (151000, 151001)
+#
