EHR migrations are among the most complex and highest-risk projects a healthcare organization undertakes. The planning cycles are long, the resource demands are significant, and the potential for disruption during go-live is well understood. What is less frequently discussed is how an EHR migration affects downtime readiness, not just during the go-live window but throughout the entire project lifecycle.
Organizations that invest in strong downtime preparedness before beginning an EHR migration often discover that the migration itself introduces new gaps in that preparedness. HL7 interfaces are rebuilt for the new system. Workflows change. Staff learn new documentation habits. Forms libraries are rebuilt. Each of these changes has direct implications for downtime continuity, and if they are not managed proactively, the organization may arrive at go-live with a downtime solution that is partially disconnected from the new EHR environment.
Understanding the specific ways an EHR migration affects downtime readiness, and what to do about each one, is an essential part of migration planning that rarely gets the attention it deserves.
Phase 1: Before the Migration Begins
The period before an EHR migration begins is the best time to assess and strengthen downtime readiness, because it is the last point of stability before everything changes. Organizations should use this window to:
- Document the current state of downtime preparedness in detail, including which HL7 message types are in use, which departments have downtime workstations, what forms are in the library, and what the post-outage recovery process looks like
- Identify which elements of the current downtime setup are tied specifically to the outgoing EHR and will need to be rebuilt for the new one
- Evaluate whether the current downtime solution vendor has documented experience integrating with the incoming EHR platform
- Confirm that the migration project plan includes specific workstreams for maintaining and rebuilding downtime preparedness at each phase
Organizations that have not yet implemented a dedicated downtime solution should treat the period before a migration as an urgent prompt to do so. The go-live window of an EHR migration is one of the highest-risk periods for unplanned downtime, and arriving at that window without a functional downtime solution in place compounds the risk significantly. dbtech’s Downtime Solution can be implemented on a focused timeline, and getting it in place before migration work begins means the organization has a stable backup environment throughout the transition.
Phase 2: During the Migration Project
The migration project itself introduces several specific downtime readiness risks that need active management:
- The HL7 interface between the current EHR and the downtime workstations may be disrupted as the EHR environment is reconfigured for migration
- Staff training and attention are heavily focused on learning the new EHR, which means downtime training tends to deprioritize and lapse
- Workflow changes made in preparation for the new EHR may not be reflected in the downtime forms library, creating a mismatch between what staff encounter on the downtime workstations and how they are now working in the live system
- The migration project team may make configuration changes to the EHR environment that affect the ADT feed and other HL7 messages without flagging the impact on the downtime integration
The most important mitigation is to assign explicit ownership of downtime readiness within the migration project team. Someone needs to be responsible for monitoring the HL7 feed throughout the migration, confirming that the downtime workstations remain current, and flagging any configuration changes that could affect the integration. Without explicit ownership, downtime readiness tends to fall through the cracks of a project that has hundreds of other competing priorities.
dbtech’s technical team works directly with migration project teams to monitor and maintain the HL7 integration throughout the migration period. For organizations using dbtech’s eForms or Managed eForms, the forms library can be updated in parallel with workflow changes, so that the downtime environment stays aligned with how staff are actually working rather than reflecting the workflows of the outgoing EHR.
Phase 3: The Go-Live Window
The go-live window of an EHR migration is the period of highest downtime risk and the moment when downtime preparedness matters most. During go-live, organizations typically experience:
- Extended planned downtime windows for the cutover from the old EHR to the new one, which can range from hours to multiple days
- Elevated rates of unplanned downtime in the weeks following go-live as the new system is stabilized and optimization work is underway
- Reduced staff proficiency with both the new EHR and the downtime procedures, because the learning curve for the new system competes with the capacity to practice backup workflows
- Increased volume of IT support calls and escalations that can delay downtime response if protocols are not clear
For the go-live window specifically, dbtech recommends that organizations treat the EHR cutover as a full downtime drill. Staff should be briefed in advance on the downtime workstation locations, the downtime forms library should be verified as current, and the HL7 integration should be confirmed as ready to connect to the new EHR as soon as it goes live.

Phase 4: After Go-Live
The post-go-live period is where many organizations discover downtime readiness gaps that were created during the migration but not caught until something goes wrong. Specific things to verify in the weeks following go-live include:
- Confirming that the HL7 integration between the new EHR and dbtech’s downtime workstations is functioning correctly and that patient data is current
- Verifying that the ADT feed is sending all expected message types from the new EHR, including admit, discharge, transfer, and update messages
- Reviewing the downtime forms library to confirm that all forms reflect the workflows of the new EHR rather than the outgoing one
- Updating department-level downtime procedures to reflect any workflow changes introduced by the new system
- Conducting a post-migration downtime drill to verify that staff can use the updated downtime environment effectively
A dbtech Downtime Audit Assessment conducted in the 30 to 60 days following go-live is one of the most effective ways to confirm that downtime readiness has been fully restored after the migration. It reviews the HL7 integration, the forms library, the workstation configuration, and the department-level procedures, and identifies any gaps that need to be addressed before the organization faces an actual unplanned outage.
