Hello Deon, If you have the chance, exporting both your layers to Postgres\Postgis, would allow you to, for each district geometry, run ST_Snap[1] against its related province geometry. With the correct tolerance, this might solve a big part of your Boundary differences.
Even tho, you would need to check the result and correct the rest of the problems manually.
