The State of Iowa

The State of Iowa is comprised of 95 different state agencies that employ over 23,500 individuals.

 With a population of over three million people, the State of Iowa, Office of the Chief Information Officer (OCIO) is tasked with supporting each agency’s mission, local cities, counties, and towns and provide cost-effective IT solutions. This includes providing IT infrastructure, network services, telecommunication tools, cloud computing, application development, support, and provisioning services to support their population. The State of Iowa released a request for proposal (RFP) for Email & Productivity Services in September 2015.  Tempus Nova submitted a proposal and was awarded a 5 year contract with OCIO.

Customer Challenges & Business Problems

The State of Iowa was operating two disparate on-premise email systems.  The state-operated an on-premise Microsoft Exchange system with multiple versions of Outlook and an on-premise GroupWise email system. This presented unique challenges from support, user experience, and interoperability perspective. Iowa’s state agencies were working as distinct entities in separate email systems and versions, authentication systems, Active Directories, and corporate address books that prevented them from seamlessly communicating. This decentralized infrastructure created complexity, resulted in increased costs to the state, and adversely affected the state’s ability to accurately plan their IT budgets. The state was also facing a compliance issue as its historical data was stored on Symantec Enterprise Vault (SEV).  Iowa needed to migrate the SEV data to another, more cost-effective solution without losing critical data. Iowa was looking for a cloud-based solution to enhance communication and collaboration across all of its agencies, stakeholders, and constituents without data loss. The state also had terabytes of data in their Symantec Enterprise Vault (SEV) repository that needed to be migrated (132,808,075 messages for Active Users; 105,085,287 messages for Inactive Users; and 402,000,000 messages in the Journal Archive). 

Tempus Nova Solution

Tempus Nova worked closely with the State of Iowa, OCIO, and agency stakeholders to validate the state’s business, technical and security requirements. Tempus Nova mapped functionality from Exchange and GroupWise to G Suite.  We deployed G Suite in six distinct transition phases per the state’s requirements targeting distinct groups of users. Tempus Nova leveraged several migration tools to accomplish the highly complex task of migrating data from two distinct email platforms Exchange and GroupWise, across multiple versions of each messaging system, as well as the state’s SEV archive system.  The use of multiple migration tools presented unique challenges and data migration errors that were previously unknown and had to be solutioned by Tempus Nova. The Google Apps Migration for Microsoft Exchange (GAMME) tool could only be run at certain times and separately from the GroupWise migration effort. The CloudMigrator tool which we used to migrate Exchange Public Folders could not be run at the same time as GAMME because it resulted in unintended and duplicate migrations of user data.  The TransVault tool used to migrate SEV data had to be leveraged after all the email, calendar and contact data were successfully migrated using the other tools. Tempus Nova performed extensive data migration testing to identify all the migration scenarios, potential outcomes, unintended consequences, and develop solutions to these unique problems.

The challenge of developing a comprehensive training program and change management strategy for users who were operating on different email systems, with different versions of user interfaces forced Tempus Nova to be innovative in our approach. We designed a comprehensive training and change management plan that empowered users to embrace the change and proactively informed them of any potential migration issues.  We created side by side Compare & Contrast one-pagers that depicted before and after functionality (here is how you create an email in Outlook or GroupWise, and here is how you create an email in G Suite). We leveraged a “what’s in it for me” strategy with the state’s users and described the benefits they would achieve by moving to G Suite. This custom approach to preparing and training users who were not technology savvy created excitement, gave them confidence on the new system, and successfully prepared them for the coming change. As part of our “no user left behind” strategy, Tempus Nova delivered onsite and virtual instructor-led training (VILT) on each application together with role-based training for executives, executive assistants, IT administrators, help desk staff, and general users.  Tempus Nova provided additional power user training to the state’s Google Guides who formed the peer to peer network within the state. 

Tempus Nova installed and configured Google Cloud Directory Sync (GCDS) in the State’s environment to enable users to be unidirectionally synchronized from the State’s multiple Active Directory (AD) sources into G Suite for seamless provisioning and deprovisioning.   Tempus Nova designed and deployed an application integration strategy to allow applications and appliances to send and receive an email in G Suite.  We worked with the state to update their SMTP relay system and served in an advisory role when the State leverage Google’s APIs to build custom application integration points. 

Lastly, Tempus Nova migrated the state’s SEV data which consisted of over 132,808,075 messages for Active Users; 105,085,287 messages for Inactive Users; and 402,000,000 messages in the state’s Journal Archive. 


Tempus Nova deployed G Suite and completed the migrations from SEV to Google Vault in November 2017 to the state’s 23,500 users. Tempus Nova’s Google Certified Deployment Specialists set up and configured the G Suite domain, enabled the core services for use, set up Google Vault, provisioned users, setup and configured GCDS and completed migrations for two distinct email platforms (exchange and GroupWise). Our Google Migration Specialists set up, configured and tested the CloudMigrator tool and migrated email, calendar, and contact data for the State of Iowa’s employees. Tempus Nova’s Google Certified Trainers and change management specialists designed a custom training approach and developed targeted communications to notify users and prepare them for the transition to G Suite. Tempus Nova provided deployment and go-live support, project management services and delivered the state’s project on time and on budget. 

The transition to G Suite enabled the State of Iowa to consolidate and modernize their messaging and archive system, achieve an annual savings of $5M, and benefit from a rolling return on their technology investment beyond just email.  The sheer complexity of this project to migrate huge amounts of data from multiple systems, using multiple migrations tools, at different times during the project demonstrated Tempus Nova’s expertise to successfully complete highly complex projects that presented challenges beyond IT.  

Customer Acknowledgment

Per Robert von Wolffradt, then Chief Information Officer for the state of Iowa “The transition to Google has saved the state millions of dollars and helped us move into the 21st century by modernizing our email system and improving the way state agencies communicate.  This was one of the most challenging IT projects I have ever seen and our partner Tempus Nova worked diligently on solutions to ensure we were successful.”
