Doing a clean install for a WPMU site with 5000+ sites, a good idea?


I have a question where I would love to hear your opinion about :slight_smile:.

We have a multi site with 5000+ sites. This site started with WPMU 2.9.2 (before it was merge in the single WP). We've updated the site till WP 3.7 and now where looking on going to 3.8.

There are some strange things happening in the site. I think this could be because the old install base, all the upgrades, plugins and all some hacks we put in the solution the last few years.

My idea is to setup a new clean install of WP 3.8 (code only) and point it to the old DB. Then update the DB and add all necessary plugins and themes to the site.

What do you think of this approach? Any risks in this?
