"MIGRATE" is still a bit awkward here, because "migrate" is historically an intransitive verb, it isn't normally used like that. I went over all keywords in lex.h again and I think this one works quite well: ALTER TABLE ... CONVERT TABLE tbl_name TO PARTITION (partition definition) ALTER TABLE ... CONVERT PARTITION part_name TO TABLE tbl_name I also think it conveys the meaning better.
