Looks like loading to same table seems easier as per your email.

Is it possible to partition existing table add data?

Well now the POS is changing to where orders are taken differently. I have made it so the data load format to the DW is the same but how some rows relate to each other have different meanings. As well as different item numbers for the same product between old and new. I plan on grouping them through a lookup table.

I have some applications where it doesn't matter how the data is, queries will still work. This makes it easy if I load to the existing table, if I don't then I will have to add a bunch of Union queries or create some kind of Materialized View. If it is two tables then it will be easier to distinguish the two and if we have very specific queries we know how each data set will behave.
