The issue you are facing:

So I just went through to process of upgrading my older nextcloud install from 10.0.0 to 11.0.2 with a stop at 10.0.3. This was my first time using the new updater and I have to say that it is very much improved from the owncloud version. However it still took over 6 hours for the script to update my server and at the start of the 10.0.0 -> 10.0.3 upgrade process I added my own logging to see why the script was 504ing. While the update does “ignore” the data folder since a RecursiveIteratorIterator is used it took my server 5 hours to loop through and "ignore’ my data folder. Is there possibly a better way to do this ?
