I uploaded my AncestryDNA test to 23andme during a DNA special they had for DNA day 2018. I believe they called this promo Discover23(at least that it how it's noted in my settings there). They did not offer matching for the uploaded tests but showed Ancestry Composition. I recently also tested with them to get myself in their database for matching purposes. Below is a comparison of the two tests. The AncestryDNA test was version 2 and the 23andme is their latest chip test.
DNA Relatives Comparison of the tests:
While the AncestryDNA upload there won't show me my matches it did show me a graphic that said I had 1165 matches which is close to the number on my match list from the test thru 23&me which lists 1177 DNA relatives.
Ethnicity Comparison of the tests:
