Revit 2020 model to Revit 2023 upgrade issue

[dheeban.raj]

Hi,

While upgrading my Revit 2020 model into Revit 2023, I am losing Electrical Panels and schedules. Is there any solution for the same.  If anyone knows how to upgrade model one version to another version can you please suggest us. 
thank you!

This may or may not help but it is recommended to upgrade incrementally by year.

If you click the help link in the error box it will explain that there was a different upgrade process in 2023 related to analytical elements, however when you explore this further it seems to be primarily related to structural analysis.

Not sure why it affects electrical panels.

Maybe someone else can elaborate.

I'm with @RobDraw on this one... try year by year until you get to 2023.
