Are PyCharm configurations compatible across OSes?

Question

PyCharm

I want to switch from Windows to Ubuntu, it's time to transfer all applications and their configurations, I got to PyCharm, but I'm worried about a few points:
1. In the export options, it has the Default project option. I understand these are the paths of my local projects, but they will be different on Ubuntu. What could be the problems with migrating this configuration?
2. I have accumulated a lot of plugins, but in the export list, I did not see the option to transfer plugins, only Material Custom Theme. How do I transfer all plugins and their configurations?
3. PyCharm has a built-in virtualenv, do I understand correctly that this is just a graphical add-on over the standard virtualenv and there shouldn't be any compatibility problems?

Answer 1

1. This is about the default template settings, they are OS-independent.
   
2. Plugins, unfortunately, only by hand, I don’t know where their settings are stored.
   
3. There is a config/options/py_sdk_settings.xmlpath to venv in the settings file, by default it is created in the project directory, and therefore transferred.
