I have 3 wordpress site on different servers, and I don't

Hi, I have 3 wordpress site on different servers, and I don’t have wordpress mulitnetwork sites.

Can I still use your plugin and seed content from one site to another or they have to be multisite network.

If I can do they seed images as well?

If none of this is working, do you know any plugin what does that?

And last one, do you reimburse money, in case I can’t use this plugin.

Tnx

Ana
