Help to alter a non partitioned table to partitioned with subpartitions

Hi,

I have a table in my MySQL 5.7 database:

create table CUSTOMERS
(
CUSTOMER_ID bigint not null,
SERVICE_ID bigint not null,
POLICY_ID bigint,
CUSTOMER_NAME varchar(255),
CREATED_ON datetime(6) not null,
primary key (CUSTOMER_ID),
unique key A_U1 (SERVICE_ID, CUSTOMER_NAME)
);

create index C_2 on CUSTOMERS
(
POLICY_ID
);

I'm looking for help to create the statements on how to change this table to be a partitioned table by list SERVICE_ID first and subpartitioned by CREATED_ON

SERVICE_ID can be one of the following numbers: 01, 02, 03, 04, 05, 06, 07, 08, 09
CREATED_DTM is a timestamp and I want the subpartitions to be daily based.

Please also let me know if I need to upgrade to MySQL 8.0 to get access to better features to do this.

Thanks in advance!
