+-- Replace stock_limit/stock_used with sla_guarantee in package_plans table
+-- This migration converts the inventory system to an SLA guarantee display
+
+-- Step 1: Add the new sla_guarantee column
+ALTER TABLE "package_plans" ADD COLUMN IF NOT EXISTS "sla_guarantee" DECIMAL(5,2);
+
+-- Step 2: Drop the old stock columns (no data migration needed as we're changing the concept entirely)
+ALTER TABLE "package_plans" DROP COLUMN IF EXISTS "stock_limit";
+ALTER TABLE "package_plans" DROP COLUMN IF EXISTS "stock_used";
