Someone already used the migrate database function in USS admin page?
I´m trying to use it to migrate my database from oracle to sql server, but with no success.
Are you getting any errors in the Liferay logs? and is anything created in SQL?
I see you are on 6.1.2, it mentions below that there are some issues on 6.1.0 GA

It also mentions below that this doesn't work on Liferay 7 either, you may want to look into a 3rd party migration tool:
