Note: It's worth noting that one must have set the proper permissions for the private messages to be imported at all.

Oddly, the messages that do get through are all addressed to user 1...

When navigating to the messages path I see only 3 pages worth of messages, which is kind of far from the 1933 that did get imported.

Clarification:

Seems the messages to user 1 are messages of old users. >See also

Nevertheless, I would expect user 1 to be able to see all messages, but this is probably related with the privatemsg module itself.

#1323442: Can only flip STRING and INTEGER values is the issue in migrate which is related to this core bug #1102570: array_flip() [function.array-flip] issue in DrupalDefaultEntityController / entity.inc

However neither of these will solve the issue for us. I think it is to do with the fact that there is no user with that ID (as suggested).

select author_id, count(*) from phpbb_privmsgs left outer join phpbb_users on author_id = user_id where user_id is null group by author_id;

Shows that with my data at least there are messages from users that no longer exist. These can't be imported as we have no details on them.

This gives us three options that I can see:

  1. Ignore records from users which don't exist.
  2. Create a dummy user for each deleted user which will be disabled
  3. Create a dummy user to use in all cases where the user has been deleted

I am tempted to go with option 1, it seems the least troublesome. At least it will be consistent with Drupal's data retention policy with deleted users.

Imho, I would go with with approach 2, as the data retention policy is configurable, isn't it?

Using 3 (same user for all messages) would be problematic I'm afraid, because the granularity per deleted user would be lost.

Sorry for bothering you again with this issue, but perhaps it would be easy to implement setting the uid for these messages to the Anonymous User (say, option 4).

Problem is, I can set the uid to 0 for topics / posts, since they are imported, but it appears privatemsgs do not all get imported for some reason (even though some do get mapped to uid 1).

If I had all private messages, I would be able to manipulate the DB to assign these entries to the Anonymous User.
