The old content can become a liability. Maybe the brand has shifted, or norms have shifted and the old content is off-key.

It was not an issue of refining the content on one site, you make a good point though.

It was more of an issue that they had a bunch of clients on an old CMS system, and they did not want to make any changes the way that the sites were built or hosted.

I can make arguments for and against either side of this idea, it all depends how you want to run your business.
