Thank you @Lilly. I’d like to know if permalinks can handle a full domain change too. Just to clarify, we’re moving from abc.domain1.com to xyz.domain2.com. Both the subdomain and the domain are changing. I’ve been reading through this discussion and wanted to confirm:
Are you trying to redirect an existing Discourse topic to an external URL? That’s not what permalinks are designed to do. I’m pretty sure that you can’t redirect anything under /t.
If you want people who visit https://hoidap.cheng.vn/t/cach-cua-do-nu-bao-binh-don-gian/70 2 to be redirected to https://cunghoangdao.info then I think your best bet is to edit the post and tell people to click the link to go to the other site.
