Connections deleted when updating from Revit 2018 to 2020 version

[Anonymous]

Hi,

Recently we have updated the software Revit 2018 to 2020. After updating when I opened my Plumbing Model, the fittings almost 20 to 30 percentage got deleted. is there no way to update model without affecting the elements from the previous versions?

Regards.

Short answer is no, but you might be able to avoid it by upgrading to 2019 before going to 2020.
