Summary of the issue you are facing:
Hello Longer time ago I wanted to do the upgrade from 27.1.4.1 to 27.11 and to go higher to catch up with the latest version. I know I’m running the old one but suddenly the upgrade is not working properly.
If I update over the web updater I end up with 27.11 accroding to the occ status but in the admin page I still have the 27.1.4.
I tried to upgrade then manually to 28 but there were tons of issues I had to solve afterwards and was not even working properly like polyfill- iconv
, opis/closure and some others. I decided to go back to orinigal 27.1.4.1
I had the original nextcloud stored as well as I had the db dump before the upgrade. I let it running as I had no time to fix it, but now finally I have time and want to ask you please for help how to proceed properly to be able to go to the latest 30. I think the issue somehow is in the 27 version for me.
