None-Partition Table to Partition Table conversion - Oracle 19c EE/RAC/AIX

Hi ,

I have none-partitioned table , that I would like to convert to a partition table. This table has about 150M rows, also has a BLOB column. The table data segment is like 400 GB and LOB segment is 1.5 TB, so total is like almost 2 TB.

I tried the latest feature to convert this table to a partition table using the alter table partition, but it was not able to do it over 24 hrs.

alter table OPEB_A modify
