Agency/Service Pre-Transition Requirements

Thank you to all agencies/services for the continued engagement with the Converge team as the TSP transitions to a new record keeper.

This is a reminder that all agencies/services will be required to send payroll files and data to a new location at the time of cutover to the new record keeper. To achieve this, each agency/service must complete the following critical actions in preparation for the transition. Failure to do so will impact an agency’s or service’s ability to make contributions to the TSP.

Critical actions required to send data to the new location include:

  1. Sign and submit Memorandum of Understanding (MOU)1 no later than October 1, 2021.
  2. If applicable, sign and submit Interconnection Security Agreement (ISA)2 no later than November 15, 2021.
  3. Participate in testing between September 2021 – March 2022 to ensure files can be sent to the new system.
  4. Participate in training, processes, and systems readiness reviews between January – May 2022.

Please note, since the March 15, 2021 Bulletin 21-1, the Converge team has been working with each agency/service individually. Any agency or service-specific timelines associated with the actions outlined above provided during these outreach efforts remain valid.

We look forward to continuing to support you throughout the transition.

  1. Agencies not currently using an ISA will require an MOU, an agreement which defines the responsibilities of two or more organizations in establishing, operating, and securing a system interconnection. With the change in TSP recordkeeper and underlying systems, the introduction of an MOU was determined as appropriate to remain current with National Institute of Standards and Technology (NIST) guidelines.

  2. An ISA is an agreement established between the organizations that own and operate connected IT systems to document the technical requirements of the interconnection. With the change in TSP recordkeeper and underlying systems, the connection between current agency IT systems and the new TSP recordkeeping system will fundamentally change, resulting in the need for a revised ISA. This ISA—for purposes of interacting with the new recordkeeper—will be in addition to the annual ISA refresh process with the current recordkeeper.
