Yes and no.
As said, I need a specific post to be the first of the merged duscussion thread.
Using the posts:reorder_posts option would place this “special” post right where it belongs in order of time, but that would be a no go.
So the list of actions should be:
- apply a new timestamp to a specific post (or posts)
- merge the topics
- run
posts:reorder_postsrake task to put everything where it belongs
The change of timestamp available today is applicable only to an entire topic, and all posts in that topic will be re-timestamped according to the delta time applied.
