After a bit of digging around I discovered that EasyBlog creates a table that cross references the old article ID's to the new ID's. This is created during the migration process and the values are stored in the '#__easyblog_migrate_content' table. Perfect for migrating the missing comments across.

Using this table I was able to change the object_id in the original jcomments table to match the new post_id for EasyBlog. I simply ran the following SQL statement from within phpMyAdmin. (You will notice that I've made a copy of the original table into the table h0ahq_oldjcomments, just in case.)
