Geostream will perform the discovery visits and provide in-depth documentation to ensure a smooth transition with re-architecture where required. We have vast experience in this field.

We understand this. We do the walking, talking, crawling, and climbing to get to every last bit of every last network. We write extensive reports and produce detailed data sheets to ensure there are no surprises during cutover, no services failing on completion. Our due diligence helps deliver a smooth transition with minimum snagging and a successful return to operation.

Network separation during divestment, though simpler, has its challenges and requires a detailed architecture plan to successfully split the networks. Main network services, such as Active Directory Domain Services, DNS, DHCP and Print, all need to be separated correctly lest servers and systems become unavailable post cutover. Handover preparation is also key to ensure the new owners of sold equipment are able to take full control without problem.

Even with the best preparation, challenges can present themselves which need to be dealt with efficiently and without disrupting the rest of cutover. We are agile engineers who can think on our feet, see around problems and provide solutions, keeping everything on track.

Enterprise operations can run 24/7 so Hypercare may need to as well. Problems need to be rectified quickly and efficiently to ensure any downtime is kept to a minimum, and those that manifest during this phase can be varied and not always of the normal break fix type, or of a single point of failure. Given the significant changes that may have occurred during cutover and the extensive dependencies and relationships between systems, the root cause of a problem may not be immediately obvious. It is important, therefore, that the support team are agile, good at working under pressure, have initiative and are multi-skilled.
Systems architects, and engineers responsible for cutover & Hypercare, will discover and produce a wealth of information covering the various servers, systems, and devices on the network, all of which needs to be documented in a clear and concise format to handover to BAU teams. As we’re a client focussed team, we also aim to pass on any concerns, observations, and recommendations that we’ve found.
