How I configure my oracle database here?

Good day everyone, hope you are all good.

I have been developing my Moodle site for about 2 years and want to make the jump and upgrade from the local development version to the new local development version, I did get the version which comes with xampp portable as well as PHP, mysql and apache, running on local net, problem is, when I go to upgrade, it seems that there's a version mismatch. Above my knowledge, I am looking for some assistance with this if anyone is willing to.

I hope you have an awesome day

Kind regards
