The Easiest D7 to D9 Image Migration Fix

Created on 30 November 2022, almost 2 years ago

Problem/Motivation

After migration the images(files) are in the public folder, but not inside the nodes.
I tried this module to fix the issue, but it wouldn't work with D9.
After looking into some other solutions I decided to check the tables in the database.
There are 2 tables, that are connected to this problem: file_usage and file_managed
By just copying data in MySQL with SQL from d7 database to d9 I was able to fix images in this "quick and dirty" way:

# file_usage tables have exactly the same fields. d7 and d9 are the names of databases. SQLs executed in SQLyog.
INSERT INTO d9.file_usage (fid, module, `type`, id, `count`)
SELECT fid, module, `type`, id, `count`
FROM d7.file_usage;

# file_managed table in D9 has a few extra fields: UUID, langcode and CHANGED.
# UUID field that was just inserted the same fid value in it.
INSERT INTO d9.file_managed (fid, UUID, langcode, uid, filename, uri, filemime, filesize, STATUS, created, CHANGED)
SELECT fid, fid, "en", uid, filename, uri, filemime, filesize, STATUS, TIMESTAMP, TIMESTAMP
FROM d7.file_managed;

After this please still verify that your images are now available inside your nodes.

Hope it would help someone as well, thanks.

    The first one ran perfectly, with thousands of rows affected, but the second one gave me an error:

    Duplicate entry '1' for key 'PRIMARY'
    

    It turned out that it was because I had uploaded a logo and favicon file. Manually deleting the records on the d9.file_managed table made it run just fine and I now have images migrated to my d9 fields. Thank you!!
