Does the program-conversion requirement in V6R1 mean you should put off your move to V6R1? That depends....
By Joe Pluta
A lot of issues have been brought to light regarding the latest release of i5/OS, perhaps none bigger than the object conversion issue. I've heard incredible amounts of static on the mailing lists about this, and it's perhaps the single most talked-about topic regarding the upgrade to V6R1. But is it really that much of an issue? I contend that, depending on whom you are, there may be much bigger fish to fry.
What level of disaster recovery and high availability capabilities do you need? Understanding RPO and RTO can help you to find the answer that best balances costs, risks, and profitability.

For a few decades now, all prudent IT departments have had some form of disaster recovery (DR) plan in place. For many companies, that still solely entails sending nightly tape backups offsite and arranging for a site, possibly one owned by a recovery service provider, where data and applications can be loaded onto systems and run should disaster strike the primary data center. Increasingly, because of more stringent regulations concerning data and system protection and because already high downtime costs are continuing to rise, organizations are augmenting DR with high availability (HA).
