Simplified Long-term Coexistence — #LotusNotes, #Office365 and Beyond

We’re frequently asked about the viability of long-term coexistence between platforms like IBM Lotus Notes, Domino, Microsoft Exchange and Office 365.

These inquiries originate from a variety of organizations and scenarios. Some examples include:

  • Growth through mergers and acquisitions
  • Long-term vendor/supplier relationships
  • Disparate departments, offices or branches with different platform requirements

However, regardless of the scenario, the concerns seem quite consistent:

  • Will we be able to quickly establish a common directory?
  • How will users be able to schedule resources across systems?
  • Are free/busy requests possible between environments?
  • What is the impact to legacy applications and workflows?
  • Is coexistence a feasible model for maintaining business productivity on a long-term basis?

Coexistence World

Many organizations going through a migration establish coexistence for a short period of time as they complete the migration project. However, entities requiring longer-term coexistence have understandable concerns about the impact to business operations and workflows. Rather than a solution to fill a temporary gap, they are looking for a new architecture and standard of operation. As a result, they want to ensure the organization will be able to flourish and grow in a coexistence world.

While there are certainly costs and considerations when maintaining and supporting multiple platforms, the good news is that long-term coexistence is a viable option, as discussed in this recent case study by Imerys and InfraScience.
