Shadowbase Zero Downtime Migration (ZDM) software provides continuous availability, eliminates planned downtime, and removes business risk from application upgrades.
Shadowbase ZDM Eliminates Planned Downtime
Shadowbase ZDM software completely eliminates planned application downtime and improves overall application availability. A large amount of system downtime is due to planned outages required for upgrades, maintenance conversions or migrations. The requirement could be for an operating system upgrade, a new application release, database maintenance or installing new hardware. With Shadowbase ZDM, these interruptions are handled without denial of application services to end users, therefore scheduled downtime is eliminated, maintaining continuous availability for IT business services. All that is needed is a location (on the same node or another node, depending on the type of conversion) for the new environment.
Shadowbase ZDM Eliminates Business Risk
As part of the ZDM process, the new environment is synchronized with the production environment using real-time change data capture and all functions are verified before the cutover occurs. Shadowbase ZDM thus eliminates the risk of the classic Big Bang conversions and outage windows by allowing the users to cutover, either gradually or all at once, to a known-working environment.
