Tonight I updated themes, plugins and promoted from staging2 the clickable carousel on the updated front page. I exported all posts from the date of imaging staging 2 (early Dec) and imported into the redeployed site. Used Duplication Pro to write a backup image to email@example.com google drive account.
This note should also test that email delivery of posts is working. Turns out I had to regenerate the Jetpack email address to reset the link. Then I updated the firstname.lastname@example.org alias with the new address. So folks need to remember to send to email@example.com.
