Currently, the document What gets migrated with Bitbucket Cloud Migration Assistant explains that LFS files are not migrated using the BCMA tool, and Git LFS can be migrated manually afterwards.

However, it would be helpful to add the link to the KB "Guide to Migrating Repositories Containing LFS from Bitbucket Data Center to Bitbucket Cloud" in the BCMA tool so users are aware that this step is necessary to view the LFS files after migration to Bitbucket Cloud.
