Now this is definitely NOT a WPMUDEV issue, but an appeal to fellow advanced multisite techies for advice in how to get out of this hole!
The situation is one of my inhouse created themes (lets say xyz-theme) has the same name as a third party theme that we want to use on the multisite.
Whats the issue just change the name of the inhouse theme directory and the name in the top of the style.css and move on?
Well, when you change the theme directory (e.g. 123-theme)the site flips over to the default theme, when you add the newly named theme 123-theme back to the sites the sidebars and menus are all defaulted too! Not a pretty sight in test.
Also very manual re-setting the theme on many sites.
Any ideas. e.g. stop the flip to default (does pro-sites do that flip?), what actually actions the flip - if no visitors can the flip be stopped? What about bulk adding back the theme?
Or am I going about this a very hard way and there is a better approach?
My multisite isn't massive but beyond manual changing of all sites and also need to test any approach carefully before breaking the live system.
