Can I switch project templates after starting a project?

Had a corrupted installation… done the reinstall. Now reconstructing project templates. In the interim, I have a saved project I’d like to move into a new project template? Is there an easy way to do this?

Running dorico 5.1.50.2150 (Jul 26 2024)
Dorico 5 AudioEngine Version 5.6.41.124
on a Mac mini m2 pro 32GB RAM, Sonoma 14.5

You can import flows from any file into any other file.

When you say “corrupted installation”, do you mean your user settings got somehow unusable, or something else? The “installed” parts of Dorico – the app, the VSTs, the sounds, etc – should all be read-only.

Apparently related to the steinberg installation and activation apps. anyway. That part is now resolved with help from steinberg.
So, do I open a project with the new template and then import the flow from the saved project? That makes sense. Okay.
