phpBB - Some threads are missing

[Problemsolver]

I believe I succesfully imported maybe 95% of all threads but realize that many larger ones were missing. I also changed the forum and subforumsorder.

Is there any way to reimport specific threads (I know which one I need)? Is here any point of doing the import again or would the result probably be the same?

The import would be the same, getting the information about which failed depends on which version of phpBB is it.
