How to move 1 site of a multi-site > other server

I have manually moved a single site of my my multi-site from my dev server to my staging server by doing the following:

* migrating any new plugin / theme / upload folders
* migrating the new tables ie; wp_xx (site id)
* updating master blog table wp_blog with the same site url/id from the dev

All works perfectly. The site loads normally. One problem remaining to resolve... in administration menu the newly added site DOES NOT appear in the dropdown menu of sites. It DOES appear however if I navigate to 'My Sites > Network Admin > Sites'

What sayeth the group ?
