Moving wordpress site to subpage of another site

This is how I would do it:

  1. Log into “other organization”
  2. install All In One WP Migration
  3. make a copy of your site
  4. download said copy
  5. In site.com Create a directory called acquiredpages
  6. install a blank copy of WordPress
  7. log into your blank wordpress
  8. install All In One WP Migration
  9. run the migration with the file from step 4.

This should work for most wordpress sites and I’ve used it to migrate dozens of client sites. Best of luck!
