Revit version compatibility for delivered models
A newer Revit file cannot be opened in an older release. The delivery version has to be agreed before modelling starts.

The most common file-format mistake on outsourced Revit work is modelling in the wrong year. The practice opens the file and Revit refuses it because it belongs to a later release. That is not a settings error. It is how the software is designed.
Two directions of compatibility
Revit is generous in one direction and strict in the other. A current release can open a model, family or template saved in an earlier year, and it upgrades that file as it opens. It cannot go the other way. There is no Save As for a previous Revit year. Once a file has been saved in 2025, a 2023 seat will not open it. That limitation applies to projects, families and templates. Autodesk’s support articles on the subject are linked below; the practical consequence for conversion work is simply to agree the year before modelling starts.
Why this matters on a conversion job
The receiving practice must be able to open the file in the Revit they actually run. If they are on Revit 2023, the model must be built and saved in 2023 (or earlier). Building it in 2026 and hoping to “save down” is not an available workflow in Revit.
Templates and families follow the same rule. A 2025 template cannot be used as the starting file for a 2023 deliverable.
IFC and DWG are not a downgrade
IFC export is for handing a model to software that is not Revit. It is not a way to produce an older .RVT. Exporting drawings to DWG likewise does not create an editable Revit project. If the practice will keep working in Revit, they need a native file in the correct year.
Questions
Yes. A later Revit release can open and upgrade an older file. The problem is only the reverse direction: newer to older.
