I have a single installation of WordPress working on a live site perfectly.
On a test domain I have succesfully installed WordPress and created a network so that I can test out the functionality etc.
I know want to 'convert' my live installation to multisite without losing significant downtime. I am running a news aggregator template so there are no posts or comments but rather all widgets (117 of them!)
I would be grateful for any advice on the best way forward.
