Adding existing configurable product to new website doesn't move configurations
Right now I have an installation with ~60 websites, and I'm looking at importing products. I'm doing some testing, and the issue I've run into is that if I have for example
Product A with 4 configurations (sizes M / L, colors Yellow / Black) exists on main website.
If I go to the "Product in Websites" section on the Product A configurable product page and add it to another website, it appears to add the configurable product to the website but not its configurations.
The result of this is I have an out of stock product on the new website. If I look at the store scope for the website I moved it to, it does show the configurations. If I actually go to the simple product for one of those configurations though, it shows that it doesn't exist on the new site.
Is there an efficient way to move the configurable product and all its configurations to all new websites in the same installation?
