Most likely yes. The connector saves posts straight into your website's own news table, so it needs to know which tables your CMS uses.
articles or news, categories and users, are recognised by the connector by itself. After pairing, the CMS line in the Connection box of your website's page in My Sites shows which one was found.Either way, AlgoPoint never creates or deletes tables or categories on your website, and the connector only changes posts it created itself. If you are unsure, add the website and pair it; you can see the result at once. See What is AlgoPoint Connect for details.
