I used the new app user data migration released with NC24. Exporting round about 900 GB, mostly pictures, took a day. Unfortunately this means that there are changes to the data before there is even the chance to get it moved. Unless of course one puts Nextcloud in maintenance mode.
Importing the data takes days. The import is running for two days now and has achieved round about 500 GB. This increased the amount of data which is outdated. And the alternative would be to dhut down the server for four days in order to have one for export and three for the import.
Migration is from a RPI4 with 4 GB RAM to an Intel based system with a celeron and 16 GB RAM.
How is you experience with the migration app in terms of performance?
