We have environment with 14.5 and now we have established totally new environment with new Ataccama 15.4. We want to migrate all the object from one environment to another without manually re-creation of objects.

Is possible to use metadata database & Audit Database of 14.5 in 15.4 Environment with some upgrade process so that all the objects can be accessed in 15.4 without any issues?

What are the steps to be taken for this?
