Switching EHRs can leave a practical gap: a clinician needs an old note, scanned document, or test result, but that information did not transfer cleanly to the new system. Full migration may not be the right answer for every historical chart. However, simply keeping an export file or backup is not enough if staff cannot reliably find and open the records they need.
To preserve access to old medical records after switching EHRs, decide what belongs in the new EHR, what can remain in a read-only legacy system, and what should go into a separate searchable archive. Then test the retrieval process as part of the transition plan, before the old system is shut down.
Choose a record-access path for each type of information
There is no single approach that fits every practice or every chart. A useful plan may combine several methods, based on how often information is needed and whether it must be available in the new system’s workflow.
- Limited structured migration: Move information clinicians need for current care into appropriate fields in the new EHR. This may include active medication information, allergies, problem lists, or recent history, depending on the practice’s needs and the capabilities of its systems. Confirm how information maps before treating the transfer as complete.
- Legacy EHR read-only access: Keep the former system available for viewing records without allowing routine edits. This can preserve the original chart context and may make it easier for staff who know the old system to locate notes and attachments. Confirm the ongoing access, support, security, and contract arrangements before relying on this option.
- Separate searchable archive: Export historical records into a system designed to store and retrieve them. An archive can be useful when the old EHR will no longer be available, but it must support practical searching and viewing, not just storage.
A practice can also use a hybrid: migrate a focused set of information for active care, while retaining older charts in a read-only system or archive. The goal is to make the right information available without assuming that every legacy field needs to be recreated in the new EHR.
Decide what staff need during a workday
Start with common care and administrative situations. Could a clinician need a prior note during an appointment? Might staff need to review an older test result, find an attachment, or respond to a records request? Which information must appear directly in the new chart, and which can be retrieved from another system when needed?
Use those scenarios to sort records into practical groups:
- Needed for current care: Identify information that should be available in the new EHR workflow. Define who reviews it and how staff will confirm it transferred accurately.
- Occasionally needed: Determine whether these records can remain in a read-only legacy EHR or a searchable archive, and establish a clear retrieval route.
- Unclear or incomplete: Flag charts with missing attachments, uncertain patient matching, or data that did not map cleanly. Assign a person to review exceptions rather than letting them disappear into a general export.
Patient matching deserves particular attention when records exist across systems. Agree on which identifiers staff will use to locate a chart and how they will handle similar names or other potential mismatches. For related guidance, see how to prevent duplicate patient charts across systems.
Make the archive usable, not just complete
A data export can contain files without providing a workable way to find them. Before choosing an archive, check how staff will search by patient and open each relevant record type. Confirm whether notes, scanned documents, test results, and attachments are included and viewable. Also ask what happens to useful context, such as dates, document types, or relationships between a note and its attachment.
Ask the outgoing vendor what data can be exported, what formats are available, and what will be required to access the records after the contract ends. Confirm whether the export includes attachments and any other information the practice expects to retain. Document the response and keep a copy of the agreed export scope. The Health IT Playbook’s EHR guidance is a useful starting point for planning an EHR transition and its data needs.
Do not treat a backup as a substitute for an archive unless staff can restore it and retrieve individual charts in a usable form. Backup and recovery planning can protect against data loss, while an archive needs a dependable way to search and view historical information. These are related needs, but they are not the same workflow.
Test retrieval before go-live
Test the archive or legacy access using representative charts before the practice depends on it. Include examples with different kinds of content, such as a note with an attachment, a scanned document, and a test result. Have the staff who will use the system try the actual tasks they expect to perform.
For each test, confirm that staff can:
- Find the correct patient using the practice’s agreed identifiers.
- Open the expected note, document, result, or attachment.
- Understand whether the record is historical and where it came from.
- Follow the documented process for requesting help when a record is missing or unreadable.
Record what failed, correct the issue, and repeat the test. Testing should also cover routine access requests, including how staff will retrieve a record when the usual person is unavailable. If the practice is still planning its new-system connection points, EHR integration planning can help frame the broader transition work.
Protect access after the switch
Historical records remain sensitive even when they are no longer part of the active EHR. Limit access to people who need it for their work, use individual accounts where available, and review who can access the legacy system or archive. Include the system in the practice’s security and backup planning, and document who is responsible for access changes, support, and recovery.
Also define how staff will handle records requests and how they will identify the authoritative record when information exists in both the new EHR and an archive. These steps matter whether the records are hosted by a vendor or stored in a separate archive.

Check retention requirements before decommissioning
Do not decide when to delete or decommission historical records based on a general rule of thumb. Requirements can depend on the practice’s profession, record type, and circumstances. Florida practices should verify the rules that apply to their specific setting and records, and consult appropriate professional or legal guidance when needed. Florida Statutes section 456.057 is a relevant starting point, not a substitute for checking which requirements apply to a particular practice.
Before ending access to the old system, confirm that the practice has the agreed export, can retrieve needed records, has documented access and release workflows, and knows who will maintain the archive. Keep the shutdown decision tied to successful testing and the practice’s retention review, not just the new EHR’s go-live date.
Frequently asked questions
Can a practice keep its old EHR in read-only mode?
Often, this is a possible approach, but it depends on the vendor’s terms, available support, and how the system can be secured. Confirm access duration and retrieval workflows before relying on it.
Which records should move into the new EHR?
Prioritize information staff need for current care and routine workflows. Decide what can remain in an archive based on how often it is needed and how quickly staff must retrieve it.
How can staff find old notes, scanned documents, and test results?
Choose a system that supports the searches staff actually use, verify that each content type is included, and test opening representative records before the transition is complete.
What should a practice get from its outgoing EHR vendor?
Confirm the export scope and format, how attachments and related information are handled, what access will remain after the contract ends, and how staff can obtain support. Put the agreed details in the transition plan.
What retention period applies to a Florida practice?
Do not assume one period applies to every practice or record. Verify requirements for the practice’s profession and record type using authoritative guidance and appropriate professional advice.
Keep the records accessible by planning the retrieval path
A successful EHR transition is not just a transfer of data. It gives staff a clear way to find historical information when care or practice operations require it, while protecting records that remain outside the new EHR.
