I was following my new proposed CHANGELOG (see decidim/decidim#9497), but I think there's some missing steps there, as the Service Worker file (sw.js) wasn't created in public/. To get it done I could do it with the following commands:

As I had doubts, I moved this question to the CHANGELOG PR: https://github.com/decidim/decidim/pull/9497/files#r909456103 (we should first solve that before merging this one, I think)

This is ready to be reviewed @ahukkanen

Thanks @andreslucena

I did not notice any issues with the upgrade itself but I had a problem with one old migration when creating the database from scratch. I first created the app using the master version, seeded it and then run this upgrade on top of it and everything went smoothly.

I'll post another PR regarding fixing the old migration when starting with a blank DB. It shouldn't be a problem when upgrading MetaDecidim itself.
