There really is nothing that need migrating. I can be as simple as install and activate (the plugin — templates are plugins) the template and then activating the template (tell Connections which to use). Excerpt Plus does have many configuration options available to tweak it to your liking, but that’s is optional. Excerpt Plus does create its image thumbnail on the fly, for a little more detail, see the exception in this FAQ. Just mentioning it in case you do like the results of the dynamic images. The FAQ basically gives instructions on how to coerce the template to give you the results you want.
I hope that helps!
Thanks for the kind words! If you have a moment, I would truly appreciate a review as they really do make a difference. Many thanks in advance!
