Hoew to migrate from 9.0

Any in how to rescue all my preferences, presets, port-setting and so on.
Tried to use xml-files of 9.0 bt that messes the system up.
Do i have to configure all the things new ?

All I can tell you is I simply copy and replaced my Plugin manager XML file from 9 to 9.5 and it worked. Now I have my old plugin lists in addition to the default. I imagine this works for any of those like preferences etc.
