Hello there !
I’m trying to migrate (files + DB) an existing Nextcloud instance to AIO.
I have checked out the following document: all-in-one/migration.md at main · nextcloud/all-in-one · GitHub
I can’t succeed in starting the Nextcloud container.
Nextcloud logs + Error:

On my host, the Nextcloud data directory is at `/mnt/ncdata`.
I have reset my Nextcloud instance several times but can’t make it work.
I was able to run Nextcloud successfully by importing only the DB and not the files. (I know I’m not supposed to start the container until the end of the migration.) It was for debug)
I have also given the right access by executing:
chown -R 33:0 /mnt/ncdatachmod -R 750 /mnt/ncdata
I have read this post too The initial Nextcloud installation failed. Nextcloid AIO startup loop but it doesn’t work.

Potential issue
One key point is identifying where the issue might be. According to the official documentation, section 7,
Now, with the containers still stopped, we are slowly starting to import your files and database. First, you need to modify the datadirectory that is stored inside the database export:
In my original database (from the original Nextcloud instance), I have entries in the database-dump.sql file that include many local:: paths.
COPY public.oc_storages (numeric_id, id, available, last_checked) FROM stdin;
1 local::/var/www/nextcloud/data/ 1 \N
2 home::admin 1 \N
3 home::user1 1 \N
4 home::user2 1 \N
5 home::user3 1 \N
7 home::user4 1 \N
9 home::user5 1 \N
35 local::/home/pi/ 1 1587842810
36 local::/opt/nextcloud-data/ 1 \N
37 local::/opt/nextcloud-data/data/ 1 \N

55 shared::dd446885af981af1d4b668a66c86b474 0 1762625136
I’m not sure why there are so many local:: entries. What’s more, only local::/opt/server-data/nextcloud/ is valid — the other directories don’t exist.
I didn’t know what to do so I edited the file like that:
COPY public.oc_storages (numeric_id, id, available, last_checked) FROM stdin;
1 local::/mnt/ncdata/ 1 \N
2 home::admin 1 \N
3 home::user1 1 \N

51 home::user7 1 \N
52 home::user8 1 \N
53 home::user9 1 \N
54 home::user10 1 \N
64 home::user11 1 \N
73 home::user12 1 \N
56 shared::c9a2767476cc24c62962c1ed327e4a98 0 1762625133
55 shared::dd446885af981af1d4b668a66c86b474 0 1762625136
Since I didn’t know what to do, I edited the file and removed the unused local:: entries. I’m not sure if that matters, because Nextcloud AIO works when I import only the database, without the files.
Do you have any idea what could be causing the issue?
Thank you for your help
