Wordpress (WPMU) Migrate & Domain Change

Goal : Using my existing provider create a Dev env of a Wordpress multisite deployment.

Prod site was two simple sites, 4-5 pages in each.  Minimal plugins.  Eventually fell upon Duplicator from Life in the Grid.

Documentation is decent and I had no issues until I started the deploy on the destination.  The decompression failed with a PHP error when I ran installer.php.  I followed the FAQ and the manual extraction process which worked fine, upload the decompressed files and archive, run the installer.php and follow the prompts.

Site 'duplicated' and working! ... almost.  The primary network site worked fine second site down.  Changed the url via the WP Network Site Admin and created the equiv subdomain entry which allowed me to browse to the second site.  Progress!

Main site :
Second site :

And then the fall.  Trying to access the WP-Admin for the second site put me into the [in]famous Wordpress login loop.  Heres a nice write up -

Followed a ton of links and tried all the suggestions with no success.  Went through the db with a forensic microscope in case a URL rename had been missed, all with no joy.  Eventually I decided to create a new site and see what the results were.  If it failed I knew it would be more WPMU than the second site setup.

Setting up site3 it was created as .. oh a sub sub domain.  The light bulb went off but I carried on.  Site3 worked fine.

Changed my second site & DNS entry to .. Golden.
