This allowed IT administrators to control the types of content with the organization, and make it more searchable and organized.

It is really important to understand what exactly your customer scenario is and then further you can plan the upgrade. By tweaking few small requirement, lots of effort can be saved and importantly, the complexity is reduced. Further, coming back to the current topic. After the upgrade was completed and after couple of month, there was a requirement to change the HUB URI of the managed metadata service. This is a quite straight forward scenario, but this requires few “After” steps. First of all, make sure that, the HUB URL is unselected in the Managed Metadata proxy properties.

Once the New Hub URI is set, It is important that the content types needs to be republished to ensure that the HUB Uri will become effective for all the content published.
