Do we have any documents which details out the steps for cloning the DB from higher environment to a lower environment DB (from Staging to Test)?

Schemas targeted are : PegaRules and PegaData.

We are trying to achieve this, but our DBAs have indicated that they will be able to do it, only if there is a document available.

Do you guys know of any such docs?

Thanks in advance.
