Support for D6's Upload module

Thumbs up!

This needs to be included.

Will this work for comment upload as well?

To answer my own question...Yes it does work for the comment upload module as well. I just had to change "field_attachments" to my comment attachment field, the database table from upload to comment_upload and changed vid to cid. It worked great! Thanks so much!

This is great! I've been trying to figure out how to do exactly this. This would be a useful addition to migrate_d2d.

This is definitely needed.

Is there a reason why attachments is often misspelled as attachements?

OK, I've added support for the upload module - if the upload table is present and the source node type has attachments enabled, source fields upload (corresponding to upload.fid), description, list, and weight are exposed as mappable fields.

Oh MikeRyan, I might have a case for you to look at!

This is using the latest dev versions of migrate, migrate_extras, migrate_d2d. Below I have included my class used and the definition I send to Migrate::register().
