Migrate Managed Metadata Service Database

Recently I came across the situation where I wanted to migrate the Managed Metadata Service database from one farm to another. Many differing solutions were mentioned on the interweb however I decided to just backup and restore the Managed Metadata database from old to new farm and see what happened. The new farm already had a Managed Metadata Service instance but had not been configured with any terms. I was also migrating a content database which had a few Managed Metadata columns and lots of items referencing the terms. I was therefore a little anxious as to whether my migrated content would display the migrated terms and if it would be possible to re-sync everything following migration or whether there might be some GUIDs that would not match. It turns out not to be so bad. Below are the steps taken to achieve this.

Backup the Managed Metadata database in old farm

Restore the Managed Metadata database in new farm overwriting the existing one

Give the account you are using db_owner permissions to the restored database

Open Central Admin and navigate to the Manage Services on Server section

Ensure that the Managed Metadata Web Service is started

Perform an IISRESET

In Central Admin navigate to the service applications page

Click on the Managed Metadata Service Application row (not the link through to the management screen)

Click on Administrators in the ribbon

Ensure that the account you are using is listed with Full Control

Click through to the Managed Metadata Service Application management page

In the Term Store Administrators section, add the account you are using

Click Save

Restore the content database

Log into the site of the restored content database

Go to Site Settings -> Site Columns where our Managed Metadata columns are listed

For each Managed Metadata column click through to the column settings page and re-link the term set anchor. You should see all migrated term sets

Your migrated content should now be showing the correct terms and you should be able to modify these values.
