Just a minor suggestion, there are no new posts on Sutra for months, so it might be retired just as well. If there’s the need/want to migrate the posts from there to here and not loose them (wonder if they can be hidden, deleted or archived/freezed), it depends on Sutra how helpful it is for such tasks (usually a main concern before using any service – can you get off of it again, can you get your data out again and move to another place easily?), but as those posts aren’t too much, they could be manually transferred, except re-creating the identities/accounts as the originators of the posts, date of publication etc. would be the usual problem.
Whatever is done, diverging attention and scattering data/conversations is bad, but migration is expensive as well, which is the typical stuckness that can be observed everywhere, and no solutions available.
