Deleting tables after import?

[peterdl]

I've successfully moved my users and posts from Nuke > phpBB > vBulletin 3.5.4 and set up my boards.

Can I now safely delete/drop all the old Nuke and phpBB tables from the MySQL database?

They are no longer nessary for vBulletin, but it'd be a good idea to keep backups period.
