Hello,

I am performing an offline migration from 2.4.17 (postgres) to 2.15.
Doing so, I receive two errors:

```
java.util.concurrent.ExecutionException:
org.eclipse.jgit.errors.MissingObjectException: Missing unknown
cbc7fc1354056a978769492d1f20ac25e46870aa
...
java.util.concurrent.ExecutionException:
org.eclipse.jgit.errors.MissingObjectException: Missing unknown
f74ecfb6ba80e9a126f4ff35864acd72161df617
```

I am guessing this is due to draft comments on two changes. I'm
alright losing those draft comments, but I'm uncertain how to remove
them from the database. Any pointers?

Best,
-Andy

Hi Andy,

As far as I'm aware, the draft comments should migrate correctly.

Can I suggest that you open a ticket (at https://bugs.chromium.org/p/gerrit/issues/list) and include the commands you used, and the full output from the migrate , and the full stack trace.

Regards

Matthew

The change 280604 definitely exists:

https://review.gerrithub.io/c/280604/

Let me check why the SHA1 can't be found.

I'll add my comments on the issue and start investigating on it more deeply at code-level.

@Luca the change does not show for me, it shows

And then I get

When I sign in.

Oh yes, I forgot that you can't see it because it belongs to a private project which is not visible to you because you don't belong to that Company.
However, trust me ... it exists :-)

Luca.
