This is how I would do it:
- Log into “other organization”
- install All In One WP Migration
- make a copy of your site
- download said copy
- In
site.com
Create a directory calledacquiredpages
- install a blank copy of WordPress
- log into your blank wordpress
- install All In One WP Migration
- 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!
