Im currently administering close to 20 separate wordpress installs and now Im at the point where I need to work out a plan going forward. As a sole operator, I just haven't had the chance to invest in this prior to now.

What Im considering is two approaches.

1) Run Wordpress in a Multi-site configuration. In this setup, Im assuming and from what I have read I will have one install on WP, plugins themes and each site that comes in uses the same database. That way I can simply update the one version of core and go from there.

2) Keep everything separate and get up to speed with WPRemote or ManageWP and manage the sites that way. This to me would fit best into my current situation and I would be able to slot it straight in.

I was hoping to get some advice form others that have gone down either route and how they found the practicality of each.

Thanks in advance.
