Not sure about migration tools, but as for what softwares to use instead of Google Docs:
For Google Docs alternatives, go for Cryptpad, Etherpad, or Framapad. This is assuming you want to be able to collaborate. Otherwise, Libreoffice (it has a nice advantage of being able to also run powerpoints and spreadsheets).
OnlyOffice I’m a bit cautious of, because while it’s a Latvian office, it may have possible ties to Russia. If there’s nothing privacysensitive, you could consider it, though - it looks very similar to Word and Google Docs!




Did you get the e/ one?
Is it possible to run e.g. GrapheneOS on it? How secure is it?
