I've just installed Yoast on my site, which I've been running SEO Title Tag plugin on.
All it does is allow me to write custom Titles. I looked at the SEO Data Transfer plugin, but it doesn't work for my theme (Default) and doesn't list the plugin I'm using either. Is there a simple way I preserve all the current custom titles, and just use the Yoast plugin for future posts/pages? It seems to work with both plugins active, but I'm sure that's not a good option if I can avoid it.
