Mergers, Acquisitions & Divestments


What is Mergers, Acquisitions & Divestments?

Mergers, acquisitions and divestments are complex. They require in-depth planning and preparation over a long period to ensure a smooth cut-over from the incumbent network to the new one or to merely sever ties with sites and services before handover.

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

  • On-site Discovery

    We travel to your site(s) no matter where they are located in the world to complete full discovery.

  • Methodical & Painstaking

    We take a careful and thorough approach with our work, and make sure everything is captured and in details even when meeting deadlines.

  • Detailed Reporting

    We provide you with detailed reports on your current set up, so you know how your network works and how to make it more secure.


Why Geostream?

We have many years of experience travelling worldwide to provide services to businesses.

Our recent engagements included working for a global food producer whose owners were standing up a new global network. We visited their factories in Africa, Asia, Europe, and North America to undertake a complete network discovery of all factory IT systems, producing professional documentation and reports. We then re-designed the networks to meet the new global requirements while still satisfying local needs and handling on-site cutover.

Our Strategy

  • Discovery

    Network and service discovery is the most painstaking phase of a network transition and is a critical foundation for the rest of the project.  All site networks must be mapped physically and logically, all switch ports accounted for, and every data socket and endpoint found.  VLANs, ACLs and NAT policies understood.  Every service known, all 3rd parties contacted, support contracts and warranties checked.  How systems integrate and which ports and protocols are used.  All of this, and more, requires a methodical and intelligent approach and cannot be rushed, no corners cut.

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

  • Architecture

    Integration architecture to join existing networks to another requires a lot of careful consideration and review.  Relying heavily on the information gathered during the discovery phase and the detailed requirements of the new network, every element needs to be compared to look for overlapping subnets, duplicate services, wireless network requirements, new policies that affect cross-VLAN communication, internet access, printing, backups and every other system.  A detailed runbook then needs to be produced that will run through every integration stage, with checkpoints, timings, and signoff responsibilities that will take the disparate networks and merge them successfully.

    Network separation during divestment, though more straightforward, has challenges and requires a detailed architecture plan to split the networks successfully.  Main network services, such as Active Directory Domain Services, DNS, DHCP and Print, must be separated correctly lest servers and systems become unavailable post-cutover.  Handover preparation is also crucial to ensure the new owners of sold equipment can take complete control without problem.

  • Cutover

    Detailed discovery documentation will enable concise runbooks, and these will help deliver a smooth cutover.  This phase happens when the offices are closed, production is stopped, and factories quiet.  Every moment of downtime can cost money, so it must go to plan and be completed as scheduled.

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

  • Hypercare

    There are two main aspects of Hypercare; to provide rapid support to ensure business continuity during snagging operations and to enable a smooth transition to the business as usual (BAU) teams.

    Enterprise operations can run 24/7, so Hyper care may also need to. Problems must be rectified quickly and efficiently to ensure downtime is kept to a minimum. Those that manifest during this phase can be varied, not always of the standard break-fix type or 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 apparent. Therefore, the support team must be agile, good at working under pressure, have initiative and be multi-skilled.

    Systems architects, and engineers responsible for cutover & Hyper care, will discover and produce a wealth of information covering the various servers, systems, and devices on the network, all of which need to be documented in a clear and concise format to hand over to BAU teams. As a client-focused team, we also aim to pass on any concerns, observations, and recommendations we’ve found.

We recently migrated to Office 365. There was barely any downtime whatsoever, thanks to Chris & Bailey. Both were very easy to deal with. So pleased with the server. I highly recommend to anyone!
