Earlier this year, I migrated a 400k post TapaTalk forum over to Discourse. TapaTalk do not offer a site backup sadly, so it had to be done through scraping the member posts from the ‘public’ side of the site. It is now pretty stable, and I thought to offer my assistance if anyone else needs to get out of the closed TapaTalk ecosystem.
Feel free to drop me a DM for any pointers or direct help.
