-- iMeeting legacy DB upgrade
-- Goal: upgrade an old schema to the latest application-facing structure
-- Strategy:
-- 1) standardize system tables to sys_* base tables
-- 2) align shared table columns/indexes
-- 3) create missing configuration tables
-- 4) migrate legacy configuration/hot-word data into new tables
-- 5) rebuild menu tree and role permissions needed by the latest backend
-- 6) recreate compatibility views

-- ----------------------------------------------------------------------
-- 1. Rename legacy system tables to sys_* base tables when needed
