HOW to import key commands from N5?

I saved my actual set of keycommands (tons of macros etc) in N5.

I tried to open the saved keycommands-file in N6: Error-Message: “This is not a key commands file”
It seems N6 is looking for a .keys file, but in N5 it is stored as an XML.

Please: How do I get my keycommands into the new version?

After you move the file, you may have to change the extension to match the N6 format. The data is exactly the same.

IIRC that worked on my upgrade.

Thank you both, that worked!
…I thought for sth like this that import/export-function was implemented…
