@ -68,7 +68,8 @@ The procedure for migrating the files and the database works like this:
1. Change it to look like this: `local::/mnt/ncdata/`.
1. Now save the file by pressing `[CTRL] + [o]` then `[ENTER]` and close nano by pressing `[CTRL] + [x]`
1. In order to make sure that everything is good, you can now run `grep "/your/old/datadir" database-dump.sql` which should not bring up further results.<br>
1. **Please note:** Unfortunately it is not possible to import a database dump from a former database owner with the name `nextcloud`. You can check if that is the case with this command: `grep "Name: oc_appconfig; Type: TABLE; Schema: public; Owner:" database-dump.sql | grep -oP 'Owner:.*$' | sed 's|Owner:||;s| ||g'`. If it returns `nextcloud`, you need to rename the owner in the dump file manually. A command like the following should work, however please note that it is possible that it will overwrite wrong lines. You can thus first check which lines it will change with `grep "Owner: nextcloud$" database-dump.sql`. If only correct looking lines get returned, feel free to change them with `sed -i 's|Owner: nextcloud$|Owner: ncadmin|' database-dump.sql`.

The same applies for the second statement, check with `grep " OWNER TO nextcloud;$" database-dump.sql` and replace with `sed -i 's| OWNER TO nextcloud;$| OWNER TO ncadmin;$|' database-dump.sql`.
1. Next, copy the database dump into the correct place and prepare the database container which will import from the database dump automatically the next container start:
```
sudo docker run --rm --volume nextcloud_aio_database_dump:/mnt/data:rw alpine rm /mnt/data/database-dump.sql
