There is a potential issue with existing customers ordering CMOD z/OS V9 - at least by using ShopZ. I'm told (but haven't seen it) that this issue may have impacted customers upgrading to CMOD z/OS 8.5 as well. Below is a note I sent out to my CMOD z/OS customers which describes the issue.
When you order CMOD z/OS V9 using ShopZ to upgrade from either 8.4, 8.4.1 or 8.5 (CMOD z/OS 8.4 & 8.4.1 go out of support 4/30/13), there may be a charge indicated on the order. There should be no charge for a like for like (same features) upgrade to CMOD z/OS V9 from any entitled SS&S 8.4, 8.4.1 or 8.5 customer. The order will then go to our zSeries Techline group who will manually "fix" the order and process it and the product should ship, or be available normally afterwards, and no charges/invoice should result.
