1. Unless the table has huge size you may please try moving the data to a
temp table and then reloading it into a new table with the desired
partitioning.
2. If it's huge, then create a separate table with desired partition and
then load data from existing table for chunks of partitions from source
table.


Hope this helps

Dev
