It's definitely easy to move, especially since page dumps are readily available and there are external tools to download all images from the wiki as well, most say its a bad idea because Wikia will 99% of the time not delete the existing wiki, which means now both will show up when users search for it, and more often than not the original Wikia site show up first. So the hardest part is not only pulling over the editor base, but the reader base as well.

I also moved to Miraheze and even got my wiki deleted, but only cause I was the only contributor to it for like the past year.
