Enterprise Infrastructure Solutions Transition

About EIS transition 

One of the government’s top priorities for telecommunications is the transition of services from the expiring Networx, WITS 3, and the Local Telecommunications Services (legacy) contracts to Enterprise Infrastructure Solutions.

The transition is an opportunity for agencies to modernize telecommunications and IT services — planning and executing an effective and efficient transition from the expiring contracts to EIS will help your agency avoid disruptions and added costs.

Authorized users

GSA updates the Networks Authorized User List [XLSX - 58 KB] of agencies authorized to use the expiring contracts (see Section H.2.3a and b of those contracts) as we enforce the eligibility condition for the extension of expiring contracts. 

Use of the expiring contracts will be further restricted by the limitations process and the freeze on modifications and orders.

Transition timeline and deadlines

All agencies using expiring contracts must meet these critical dates to ensure services are transitioned to EIS or another contract vehicle without impact to mission operations:

Several local telecommunications contracts are set to expire before May 31, 2026, and will not be extended. Agencies with inventory on a contract ending before May 31, 2026 must transition services on the contract before the contract end date. To learn more about these contract expiration dates and how they may impact your services, visit the Networx, WITS, and Local Telecommunications section of our Legacy IT Contracts page.

Transition support

We will manage the transition timeline and help agencies transition existing services to the replacement EIS contracts to ensure continuity of services. 

• Our dedicated team of solutions brokers can help navigate your agency’s telecom acquisition and execute task orders.
• Contact your Public Buildings Service National Account Manager after task order award to plan for infrastructure upgrades.

Transition Coordination Center

The Transition Coordination Center provides customer support, training, self-help tools, and templates to transition agencies. We can help you:

• Collect, validate, and maintain the transition inventory that reflects active services on all expiring contracts.
• Collaborate with contractors to facilitate a successful transition.
• Execute transition strategy and project management.
• Select contractors and place orders.
• Track and report transition progress, transition inventory, and all agency inventory.

Transition inventory

We maintain a transition inventory to capture expiring Networx, WITS 3, and Local Telecommunications Services contracts. 

TI is a collection of agency data compiled at the Service Instance Record level. A SIR reflects a summarized roll-up of a current base service composed of legacy contract data for both active and disconnected services. We validate the TI monthly and update data to account for new records, disconnected services, and changes.

E-MORRIS

Authorized agency users can access the TI using the E-MORRIS application. Each agency needs to have at least one user with E-MORRIS access in order to manage the TI data. GSA recommends having multiple users with E-MORRIS accounts as backup. These users can access and download TI data, and view transition progress tracking statistics based on the AB Codes and AHCs identified during the registration process.

Each agency was expected to review and confirm the validated TI no later than October 31, 2016. The TI is used for tracking and reporting transition progress, so your agency should continue to monitor TI for accuracy and:

• Identify agency points of contact responsible for managing the transition inventory.
• Identify exceptions and missing inventory.
• Update or requesting access to E-MORRIS and the TI module.
• Retrieve and review the data to confirm ongoing updates and changes.
• Provide feedback to the GSA Transition Coordination Center.

All Agency Inventory

The All Agency Inventory extends current TI SIRs to a more detailed level. The data is based on active services only and does not include disconnects. AAI data includes Contract Line Item Numbers, Service Enabling Device CLINs, features, bandwidth, and other data elements not included in TI. AAI data can help agencies develop Fair Opportunity solicitations and subsequent service orders.

AAI uses business rules, technical specifications, and contract requirements to transform data received from contractor inventory, billing, and orders for expiring contracts into a common format, thereby reducing the need for individual agency data collection and saving time. Data is normalized using relationships and other attributes to reduce data redundancy and improve data integrity. Current contract data is mapped to primary and secondary EIS services, CLINs, Core Based Statistical Areas, and other contract components.

Contact your GSA solutions broker to discuss your agency’s FO requirements and request AAI from the TCC inventory team.

Our All Agency Inventory user guide [PDF - 1 MB] explains the components of AAI, including data sources, available data fields, reports, the process to request AAI, and how to report issues.

Transition progress

The EIS Transition Progress Tracking Report [DOCX - 2 MB] provides a monthly status of transition progress from the expiring Networx, WITS 3, and Local Telecommunications Services contracts.

Transition is complete when:

• 100% of Transition Inventory Service Instance Records have been disconnected as reported by Networx, WITS 3, and Local Telecommunications Services.
• Business Volume Reduction reaches 100%.

As of 12/31/2025, there are 201 agencies that have completed transition, including 7 large, 23 medium, and 171 small. Completed transitions can be searched below.
