How to Handle Posts that Already Exist
I completely get it that there could be situations when you already have post duplicates or product duplicates on the other sites. Maybe you created them manually, maybe not, it doesn’t matter.
How to connect them to sync the changes? Of course, you can delete a post manually and then crosspost it again, but it seems like a lot of things to do. Another option is to set Connection type in plugin settings to SKU, but it works only for WooCommerce.

But in most cases, you can just install and activate a free-on from below. This one is in case you’re using the multisite version of my crossposting plugin:
Download Simple Multisite Crossposting – Post Connections 1.4
The second one – for the regular version:
Download Simple WP Crossposting – Post Connections 2.0
However, there are also WP-CLI commands available.
Once you are done with configuring the plugin, you can bulk-connect your posts.
The add-on for Simple WP Crossposting will also work great if you need to fix image connections. For example, when you crossposted an image from “Site 1” to “Site 2”, then your image was removed manually from “Site 2” or even reuploaded there again (not crossposted), then when you crosspost your posts, you might notice that images are getting broken – it is because my plugin remembers a certain image ID which does not exist anymore on “Site 2”. To fix it, you need to switch to the “List view” in the Media > Library page.
The same way, as with the posts – the images must have the same slugs to be connected, plus, after you have connected them, you may need to update (re-sync) affected posts.
