Moving Feedwordpress Posts to different domain

Hi –

I have a number of syndicated posts that were created via Feedwordpress that I would like to move to a different webpage.

In my case, I would like to move them to a subdirectory that is part of a multisite setup. So for example, I would like to move all of the syndicated posts that are currently located at https://www.example.com/alpha/ to https://www.example.com/subdirectory/alpha/

Ideas would be appreciated. Thanks.
