XF 1.5 Some avatars were not imported

[Triops]

At my final migration today, for the first time, some (lots) of avatars were not migrated. A lot seem to be there, but a lot do not. Eg. one of my own users lost it's avatar.
Importing avatars took full 12 minutes, which was 12x longer than before - maybe an addon caused problems and delayed the import/produce errors with Google.

So, I won't find out.
Can I import that avatars again somehow, or copy? How do I find out, what members do not got their avatar migrated?

Thank you very much,
this is urgent please,

Markus

Unfortunately the only way to bring the avatars across would be to do a full re-import. Beyond that, it'd likely require custom development to do something after the fact.
