For others attempting this, I first created my parent and child structure. Then inserted the data from the original table into the child tables. Once I was happy with my new structure I drop the original table. (which is still backed just in case) I found a couple of areas I'd missed on reading about partitions. First, no primary key. That was a big surprise. Second, my triggers I use to catch information going into the table, needed to be pointed at the child tables. I also leaned that my range partition value I used on a timestamp needed to have fractional seconds. I used a range of 2017-01-01 00:00:00 to 2017-23:59:59 which failed when I attempted to add a record that had a timestamp of 2017-23:59:59. Adding a fractional second to the range solved the problem.
